Machine learning (ML) has become a widely used tool in meteorological research and often makes better predictions than thecompeting methods. Despite this, many meteorologists are reluctant to adopt ML in day-to-day operations, due to the per- ception thatthe models are “black boxes” (cannot explain their decisions to the user). My recent work in ML interpretation […]
Title: Regional Characteristics of Flash Droughts Across the United States Abstract: Flash droughts are characterized by the rapid onset and development of drought conditions. When a combination of extreme atmospheric anomalies (such as lack of rainfall, higher surface temperatures, higher surface wind speeds, and higher vapor pressure deficient) persist for several weeks, rapid depletion […]
Convective Meteorology (Mesoscale Dynamics) Seminar Satellite Data Assimilation, Verification, and Applications Dr. Thomas Jones
Determining the effectiveness of satellite remote sensing products to quantify aerosol pollution in the semi-arid western U.S.
Anomalous charge structures, those containing net positive charge in the mid-levels (-10 °C to -30 °C) and promoting positive cloud-to-ground flashes, have been associated with updrafts producing abundant supercooled liquid water. However, surrounding the updraft core many processes act to limit supercooled liquid water content (e.g. locally lower updraft velocities, ingestion of cloud ice, entrainment) […]
Weather and Climate Seminar Characterization of the Structure of Tropopause Polar Vortices using Remote Sensing Ryan Pajela Wednesday, January 30th 3:00pm/NWC 5930 Tropopause polar vortices (TPVs) are atmospheric coherent vortex-like structures originating poleward of the jet stream and exhibit a closed circulation of the wind along the 2-PVU dynamic tropopause. Cyclonic […]
