@article{allen_yuter_miller_tomkins_2024, title={Objective identification of pressure wave events from networks of 1 Hz, high-precision sensors}, volume={17}, ISSN={["1867-8548"]}, url={https://doi.org/10.5194/amt-17-113-2024}, DOI={10.5194/amt-17-113-2024}, abstractNote={Abstract. Mesoscale pressure waves, including atmospheric gravity waves, outflow and frontal passages, and wake lows, are outputs of and can potentially modify clouds and precipitation. The vertical motions associated with these waves can modify the temperature and relative humidity of air parcels and thus yield potentially irreversible changes to the cloud and precipitation content of those parcels. A wavelet-based method for identifying and tracking these types of wave signals in time series data from networks of low-cost, high-precision (0.8 Pa noise floor, 1 Hz recording frequency) pressure sensors is demonstrated. Strong wavelet signals are identified using a wave-period-dependent (i.e., frequency-dependent) threshold, and then those signals are extracted by inverting the wavelet transform. Wave periods between 1 and 120 min were analyzed – a range which could capture acoustic, acoustic-gravity, and gravity wave modes. After extracting the signals from a network of pressure sensors, the cross-correlation function is used to estimate the time difference between the wave passage at each pressure sensor. From those time differences, the wave phase velocity vector is calculated using a least-squares fit. If the fitting error is sufficiently small (thresholds of RMSE < 90 s and NRMSE < 0.1 were used), then a wave event is considered robust and trackable. We present examples of tracked wave events, including a Lamb wave caused by the Hunga Tonga volcanic eruption in January 2020, a gravity wave train, an outflow boundary passage, a frontal passage, and a cold front passage. The data and processing techniques presented here can have research applications in wave climatology and testing associations between waves and atmospheric phenomena. }, number={1}, journal={ATMOSPHERIC MEASUREMENT TECHNIQUES}, author={Allen, Luke R. and Yuter, Sandra E. and Miller, Matthew A. and Tomkins, Laura M.}, year={2024}, month={Jan}, pages={113–134} } @article{mcmurdie_heymsfield_yorks_braun_skofronick-jackson_rauber_yuter_colle_mcfarquhar_poellot_et al._2022, title={Chasing Snowstorms The Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) Campaign}, volume={103}, ISSN={["1520-0477"]}, DOI={10.1175/BAMS-D-20-0246.1}, abstractNote={Abstract}, number={5}, journal={BULLETIN OF THE AMERICAN METEOROLOGICAL SOCIETY}, author={McMurdie, Lynn A. and Heymsfield, Gerald M. and Yorks, John E. and Braun, Scott A. and Skofronick-Jackson, Gail and Rauber, Robert M. and Yuter, Sandra and Colle, Brian and McFarquhar, Greg M. and Poellot, Michael and et al.}, year={2022}, month={May}, pages={E1243–E1269} } @article{miller_yuter_hoban_tomkins_colle_2022, title={Detecting wave features in Doppler radial velocity radar observations}, volume={15}, ISSN={["1867-8548"]}, url={https://doi.org/10.5194/amt-15-1689-2022}, DOI={10.5194/amt-15-1689-2022}, abstractNote={Abstract. Mesoscale, wave-like perturbations in horizontal air motions in the troposphere (velocity waves) are associated with vertical velocity, temperature, and pressure perturbations that can initiate or enhance precipitation within clouds. The ability to detect velocity waves from horizontal wind information is an important tool for atmospheric research and weather forecasting. This paper presents a method to routinely detect velocity waves using Doppler radial velocity data from a scanning weather radar. The method utilizes the difference field between consecutive position plan indicator (PPI) scans at a given elevation angle. Using the difference between fields a few minutes apart highlights small-scale perturbations associated with waves because the larger-scale wind field changes more slowly. Image filtering retains larger contiguous velocity bands and discards noise. Wave detection scales are limited by the size of the temporal difference relative to the wave motion and the radar resolution volume size. }, number={6}, journal={ATMOSPHERIC MEASUREMENT TECHNIQUES}, publisher={Copernicus GmbH}, author={Miller, Matthew A. and Yuter, Sandra E. and Hoban, Nicole P. and Tomkins, Laura M. and Colle, Brian A.}, year={2022}, month={Mar}, pages={1689–1702} } @article{tomkins_yuter_miller_allen_2022, title={Image muting of mixed precipitation to improve identification of regions of heavy snow in radar data}, volume={15}, ISSN={["1867-8548"]}, url={https://doi.org/10.5194/amt-15-5515-2022}, DOI={10.5194/amt-15-5515-2022}, abstractNote={Abstract. In winter storms, enhanced radar reflectivity is often associated with heavy snow. However, some higher reflectivities are the result of mixed precipitation including melting snow. The correlation coefficient (a dual-polarization radar variable) can identify regions of mixed precipitation, but this information is usually presented separately from reflectivity. Especially under time pressure, radar data users can mistake regions of mixed precipitation for heavy snow because of the high cognitive load associated with comparing data in two fields while simultaneously attempting to discount a portion of the high reflectivity values. We developed an image muting method for regional radar maps that visually de-emphasizes the high reflectivity values associated with mixed precipitation. These image muted depictions of winter storm precipitation structures are useful for analyzing regions of heavy snow and monitoring real-time weather conditions.}, number={18}, journal={ATMOSPHERIC MEASUREMENT TECHNIQUES}, author={Tomkins, Laura M. and Yuter, Sandra E. and Miller, Matthew A. and Allen, Luke R.}, year={2022}, month={Sep}, pages={5515–5525} } @article{hueholt_yuter_miller_2022, title={Revisiting Diagrams of Ice Growth Environments}, volume={103}, ISSN={["1520-0477"]}, DOI={10.1175/BAMS-D-21-0271.1}, abstractNote={Abstract}, number={11}, journal={BULLETIN OF THE AMERICAN METEOROLOGICAL SOCIETY}, author={Hueholt, Daniel M. and Yuter, Sandra E. and Miller, Matthew A.}, year={2022}, month={Nov}, pages={E2584–E2603} } @article{perry_yuter_matthews_wagnon_khadka_aryal_shrestha_tait_miller_o'neill_et al._2021, title={Direct observations of a Mt Everest snowstorm from the world's highestsurface-basedradar observations}, volume={76}, ISSN={["1477-8696"]}, DOI={10.1002/wea.3854}, abstractNote={L.

Precipitation type, diurnality, frequency, and amount influence hydrological runoff, surface albedo, and soil moisture, whereas cloud cover associated with precipitation events reduces solar irradiance at the surface. Considerable uncertainty remains in the multiscale atmospheric processes influencing precipitation patterns and their associated regional variability in the tropical Andes—particularly related to precipitation phase, timing, and vertical structure. Using data from a variety of sources—including new citizen science precipitation stations; new high-elevation comprehensive precipitation monitoring stations at Chacaltaya, Bolivia, and the Quelccaya Ice Cap, Peru; and a vertically pointing Micro Rain Radar—this article synthesizes findings from interdisciplinary research activities in the Cordillera Real of Bolivia and the Cordillera Vilcanota of Peru related to the following two research questions: (1) How do the temporal patterns, moisture source regions, and El Niño-Southern Oscillation relationships with precipitation occurrence vary? (2) What is the vertical structure (e.g., reflectivity, Doppler velocity, melting layer heights) of tropical Andean precipitation and how does it evolve temporally? Results indicate that much of the heavy precipitation occurs at night, is stratiform rather than convective in structure, and is associated with Amazonian moisture influx from the north and northwest.

Acquisition of accurate raindrop fall speed measurements outdoors in natural rain by means of moderate-cost and easy-to-use devices represents a long-standing and challenging issue in the meteorological community. Feasibility experiments were conducted to evaluate the indoor accuracy of fall speed measurements made with a high-speed camera and to evaluate its capability for outdoor applications. An indoor experiment operating in calm conditions showed that the high-speed imaging technique can provide fall speed measurements with a mean error of 4.1–9.7 % compared to Gunn and Kinzer's empirical fall-speed–size relationship for typical sizes of rain and drizzle drops. Results obtained using the same apparatus outside in summer afternoon showers indicated larger positive and negative velocity deviations compared to the indoor measurements. These observed deviations suggest that ambient flow and turbulence play a role in modifying drop fall speeds which can be quantified with future outdoor high-speed camera measurements. Because the fall speed measurements, as presented in this article, are analyzed on the basis of tracking individual, specific raindrops, sampling uncertainties commonly found in the widely adopted optical disdrometers can be significantly mitigated. }, number={4}, journal={ATMOSPHERIC MEASUREMENT TECHNIQUES}, author={Yu, Cheng-Ku and Hsieh, Pei-Rong and Yuter, Sandra E. and Cheng, Lin-Wen and Tsai, Chia-Lun and Lin, Che-Yu and Chen, Ying}, year={2016}, pages={1755–1766} } @article{wood_jensen_wang_bretherton_burrows_del genio_fridlind_ghan_ghate_kollias_et al._2016, title={PLANNING THE NEXT DECADE OF COORDINATED RESEARCH TO BETTER UNDERSTAND AND SIMULATE MARINE LOW CLOUDS}, volume={97}, ISSN={["1520-0477"]}, DOI={10.1175/bams-d-16-0160.1}, abstractNote={Seventeen experts from communities focused on improving understanding and 6 modeling of processes controlling marine low clouds met to discuss future research 7 directions.}, number={9}, journal={BULLETIN OF THE AMERICAN METEOROLOGICAL SOCIETY}, author={Wood, Robert and Jensen, Michael P. and Wang, Jian and Bretherton, Christopher S. and Burrows, Susannah M. and Del Genio, Anthony D. and Fridlind, Ann M. and Ghan, Steven J. and Ghate, Virendra P. and Kollias, Pavlos and et al.}, year={2016}, month={Sep}, pages={1699–1702} } @article{szoeke_verlinden_yuter_mechem_2016, title={The Time Scales of Variability of Marine Low Clouds}, volume={29}, ISSN={["1520-0442"]}, DOI={10.1175/jcli-d-15-0460.1}, abstractNote={Abstract}, number={18}, journal={JOURNAL OF CLIMATE}, author={Szoeke, Simon P. and Verlinden, Kathryn L. and Yuter, Sandra E. and Mechem, David B.}, year={2016}, month={Sep}, pages={6463–6481} } @article{wood_wyant_bretherton_remillard_kollias_fletcher_stemmler_szoeke_yuter_miller_et al._2015, title={CLOUDS, AEROSOLS, AND PRECIPITATION IN THE MARINE BOUNDARY LAYER An ARM Mobile Facility Deployment}, volume={96}, ISSN={["1520-0477"]}, DOI={10.1175/bams-d-13-00180.1}, abstractNote={Abstract}, number={3}, journal={BULLETIN OF THE AMERICAN METEOROLOGICAL SOCIETY}, author={Wood, Robert and Wyant, Matthew and Bretherton, Christopher S. and Remillard, Jasmine and Kollias, Pavlos and Fletcher, Jennifer and Stemmler, Jayson and Szoeke, Simone and Yuter, Sandra and Miller, Matthew and et al.}, year={2015}, month={Mar}, pages={419–439} } @article{wilbanks_yuter_szoeke_brewer_miller_hall_burleyson_2015, title={Near-Surface Density Currents Observed in the Southeast Pacific Stratocumulus-Topped Marine Boundary Layer*}, volume={143}, ISSN={["1520-0493"]}, DOI={10.1175/mwr-d-14-00359.1}, abstractNote={Abstract}, number={9}, journal={MONTHLY WEATHER REVIEW}, publisher={American Meteorological Society}, author={Wilbanks, Matt C. and Yuter, Sandra E. and Szoeke, Simon P. and Brewer, W.

This empirical study demonstrates the feasibility of using 89-GHz Advanced Microwave Scanning Radiometer–Earth Observing System (AMSR-E) passive microwave brightness temperature data to detect heavily drizzling cells within subtropical marine stratocumulus. For the purpose of this paper, we define heavily drizzling cells as areas ≥ 6 km × 4 km with C-band Z > 0 dBZ; equivalent to > 0.084 mm h−1. A binary heavy drizzle product is described that can be used to determine areal and feature statistics of drizzle cells within the major marine stratocumulus regions. Current satellite liquid water path (LWP) and cloud radar products capable of detecting drizzle are either lacking in resolution (AMSR-E LWP), diurnal coverage (MODIS LWP), or spatial coverage (CloudSat). The AMSR-E 89-GHz data set at 6 km × 4 km spatial resolution is sufficient for resolving individual heavily drizzling cells. Radiant emission at 89 GHz by liquid-water cloud and precipitation particles from drizzling cells in marine stratocumulus regions yields local maxima in brightness temperature against an otherwise cloud-free background brightness temperature. The background brightness temperature is primarily constrained by column-integrated water vapor for moderate sea surface temperatures. Clouds containing ice are screened out. Once heavily drizzling pixels are identified, connected pixels are grouped into discrete drizzle cell features. The identified drizzle cells are used in turn to determine several spatial statistics for each satellite scene, including drizzle cell number and size distribution. The identification of heavily drizzling cells within marine stratocumulus regions with satellite data facilitates analysis of seasonal and regional drizzle cell occurrence and the interrelation between drizzle and changes in cloud fraction. }, number={1}, journal={ATMOSPHERIC MEASUREMENT TECHNIQUES}, author={Miller, M.

Accumulation is reasonably well captured by daily reporting rain gauges, but rainfall intensity is not. Ten years of data from the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR) are used to describe the spatial and seasonal distributions of instantaneous rainfall intensity with an emphasis on how these differ from the distributions of mean daily accumulation. Over tropical land, the rainy season, when rainfall is most frequent, does not coincide with the highest mean intensity. Rather, intensity peaks just before the rainy season. This offset is most obvious in the pre‐onset and post‐onset months in monsoon regions and it is also evident in equatorial regions without a well‐defined dry and rainy season. Most seasonal variations in rainfall intensity can be explained as parallel variations in the occurrence of convective, relative to stratiform, precipitation. However, regional differences in rainfall intensity are related to differences in the intensity of convection itself. Compared with seasonal changes in intensity over land, variations in convective precipitation fraction over tropical oceans are trivial, and the modest seasonal changes in the intensity of rainfall parallel those of frequency. These findings suggest that studies of precipitation extremes under global warming should (1) explicitly tackle the question of changes in the intensity of rainfall separately from changes in daily rainfall accumulation and (2) consider the different qualities of extreme precipitation events over ocean and over land.}, number={17}, journal={JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES}, author={Biasutti, Michela and Yuter, Sandra E.}, year={2013}, month={Sep}, pages={9534–9551} } @article{sobel_burleyson_yuter_biasutti_2013, title={Rain on small tropical islands (vol 118, pg 2301, 2013)}, volume={118}, ISSN={["2169-897X"]}, DOI={10.1002/jgrd.50205}, abstractNote={Key Points}, number={5}, journal={JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES}, author={Sobel, A.

To address this challenge, the World Climate Research Programme (WCRP) and The Observing System Research and Predictability Experiment (THORPEX) of the World Weather Research Programme (WWRP) are conducting a joint research activity consisting of a focus period approach along with an integrated research framework tailored to exploit the vast amounts of existing observations, expanding computational resources, and the development of new, high-resolution modeling frameworks. The objective of the Year of Tropical Convection (YOTC) is to use these constructs to advance the characterization, modeling, parameterization, and prediction of multiscale tropical convection, including relevant two-way interactions between tropical and extratropical systems. This article highlights the diverse array of scientifically interesting and socially important weather and climate events associated with the WCRP–WWRP/THORPEX YOTC period of interest: May 2008–April 2010. Notable during this 2-yr period was the change from cool to warm El Niño– Southern Oscillation (ENSO) states and the associated modulation of a wide range of smaller time- and space-scale tropical convection features. This period included a near-record-setting wet North American monsoon in 2008 and a very severe monsoon drought in India in 2009. There was also a plethora of tropical wave activity, including easterly waves, the Madden–Julian oscillation, and convectively coupled equatorial wave interactions. Numerous cases of high-impact rainfall events occurred along with notable features in the tropical cyclone record. The intent of this article is to highlight these features and phenomena, and in turn promote their interrogation via theory, observations, and models in concert with the YOTC program so that improved understanding and pre- dictions of tropical convection can be afforded.}, number={8}, journal={BULLETIN OF THE AMERICAN METEOROLOGICAL SOCIETY}, author={Waliser, Duane E. and Moncrieff, Mitchell W. and Burridge, David and Fink, Andreas H. and Gochis, Dave and Goswami, B.

Islands with areas between one hundred and several thousand km2 are considered in both the Indo-Pacific Maritime Continent and Caribbean regions. Annual mean climatological (1997–2007) rainfall over each island is compared with that over the surrounding ocean region, and the difference is expressed as a percentage. In addition to total rainfall, rain frequency and intensity are also analyzed. Results are stratified into two 12 h halves of the diurnal cycle as well as eight 3 h periods, and also by a measure of each island's topographic relief. In both regions, there is a clear difference between larger islands (areas of a few hundred km2 or greater) and smaller ones. Both rain frequency and total rainfall are significantly enhanced over larger islands compared to the surrounding ocean. For smaller islands the enhancement is either negligibly small, statistically insignificant, or, in the case of Caribbean rain frequency, negative. The enhancement in total rainfall over larger islands is partly attributable to greater frequency and partly to greater intensity. A diurnal cycle in island enhancement is evident in frequency but not intensity, except over small Caribbean islands where the converse is true. For the larger islands, higher orography is associated with greater rainfall enhancements. The orographic effect is larger (percentagewise) in the Caribbean than in the Maritime Continent. Orographic precipitation enhancement manifests more strongly as increased frequency of precipitation rather than increased intensity and is present at night as well as during the day. The lack of a clear diurnal cycle in orographic enhancement suggests that much of the orographic rainfall enhancement is attributable to mechanically forced upslope flow rather than elevated surface heating.}, journal={JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES}, author={Sobel, A.

The VAMOS1 Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx) was an international field program designed to make observations of poorly understood but critical components of the coupled climate system of the southeast Pacific. This region is characterized by strong coastal upwelling, the coolest SSTs in the tropical belt, and is home to the largest subtropical stratocumulus deck on Earth. The field intensive phase of VOCALS-REx took place during October and November 2008 and constitutes a critical part of a broader CLIVAR program (VOCALS) designed to develop and promote scientific activities leading to improved understanding, model simulations, and predictions of the southeastern Pacific (SEP) coupled ocean-atmosphere-land system, on diurnal to interannual timescales. The other major components of VOCALS are a modeling program with a model hierarchy ranging from the local to global scales, and a suite of extended observations from regular research cruises, instrumented moorings, and satellites. The two central themes of VOCALS-REx focus upon (a) links between aerosols, clouds and precipitation and their impacts on marine stratocumulus radiative properties, and (b) physical and chemical couplings between the upper ocean and the lower atmosphere, including the role that mesoscale ocean eddies play. A set of hypotheses designed to be tested with the combined field, monitoring and modeling work in VOCALS is presented here. A further goal of VOCALS-REx is to provide datasets for the evaluation and improvement of large-scale numerical models. VOCALS-REx involved five research aircraft, two ships and two surface sites in northern Chile. We describe the instrument payloads and key mission strategies for these platforms and give a summary of the missions conducted. 1 Variability of the American Monsoon Systems, an international CLIVAR program. }, number={2}, journal={ATMOSPHERIC CHEMISTRY AND PHYSICS}, author={Wood, R. and Mechoso, C.
