The Utility of Ensemble – Sensitivity Analysis for Targeted Observing, Ensemble Sub setting , and Diagnosing Environmental Controls on Storm Characteristics
September 25, 2018 11:00 am
CIRA Directors Conference Room
Presented by: Aaron J. Hill
Hosted by:
Texas Tech University
Abstract At Texas Tech University, we are interested in developing and using novel ensemble tools to improve our understanding of severe storm predictability. Ensemble sensitivity is one such tool that when applied within an ensemble framework reveals atmospheric flow features (e.g. position of a jet streak, or magnitude of a low-level moisture plume) at early forecast times that are related to a chosen forecast response later in the… Read more »
Precipitation Processes in Cyclones Passing over a Coastal Mountain Range: Recent Results from the Olympic Mountains Experiment (OLYMPEX)
September 18, 2018 2:00 pm
ATS room 101
Presented by: Lynn McMurdie
Hosted by: Kristen Rasmussen
Visiting ATS from the University of Washington
The Olympic Mountains Experiment (OLYMPEX) was a multi-faceted, international, multi-agency field campaign that took place over the Olympic Mountains in the Pacific Northwest during the fall 2015 and continued through the winter 2016. The goals of OLYMPEX were to provide physical validation and verification of satellite-derived precipitation measurements by the Global Precipitation Measurement (GPM) satellites and to document the precipitation processes in land-falling wintertime cyclones as they approach land and… Read more »
Deep Learning and Novel Data Analytics for Climate Science
September 17, 2018 3:00 pm
ATS room 101
Presented by: Karthik Kashinath
Hosted by: Ben Toms and Aryeh Drager
Visiting ATS from the Lawrence Berkeley National Laboratory
In this talk we discuss how machine learning, deep learning and novel data-driven analytics from applied math and physics can be used for two fundamental challenges in climate and weather sciences: (i) pattern recognition, pattern discovery and pattern tracking in large climate datasets, and (ii) emulation of complex dynamical processes that are critical for modeling Earth’s weather and climate. Part-1: Detecting, classifying and characterizing weather and climate patterns is a… Read more »
Ongoing Research into New and Emerging Technologies Aimed at Improving Scientific Research, Results, and Applications
September 17, 2018 10:30 am
CIRA Directors Conference Room
Presented by: Jebb Stewart
Hosted by:
Sr. Research Associate
At the Earth System Research Laboratory (ESRL), within the Advanced Technology Outreach (ATO) branch, research is ongoing into new and emerging technologies aimed at improving scientific research, results, and applications. These efforts range from improving data access and visualization through the development of high-performance web services, using machine learning to extract more relevant information from satellite observations, as well as the development of software containers for the ease of application… Read more »
How Strong are the Strongest Wind Gusts within Tropical Cyclones?
May 24, 2018 1:30 pm
CIRA Directors Conference Room
Presented by: Daniel Stern
Hosted by:
University Corporation for Atmospheric Research
The most intense tropical cyclones are characterized by maximum 1-minute mean surface (10-meter) wind speeds of 70-90 ms-1. Dropsondes within the boundary layer occasionally sample gusts (representative of timescales of a few seconds) exceeding 90 ms-1 and (more rarely) 100 ms-1. Such extreme wind gusts are found in nearly every category-5 tropical cyclone, but because of irregular and sparse sampling, it is unclear how frequent these gusts are, or whether… Read more »
