Part 2: Preliminary Analysis of Wind Gusts in Recent Landfalling Hurricanes
August 19, 2019 3:00 pm
CIRA Director’s Conference Room
Presented by: John Kaplan
Hosted by:
NOAA/AOML/Hurricane Research Division
Forecasting the timing and magnitude of tropical cyclone rapid intensification (RI) remains an ongoing forecasting problem. Although the ability of deterministic tropical cyclone intensity models to forecast such events has improved, their skill remains inadequate. Thus, forecasters have relied on other tools such as the SHIPS suite of probabilistic statistical rapid intensity models to aid… Read more »

Overview of the Joint Typhoon Warning Center (JTWC)
August 15, 2019 10:30 am
CIRA Director’s Conference Room
Presented by: Capt. Amanda Nelson of the USAF
Hosted by: Dr. Kate Musgrave, CIRA
The Joint Typhoon Warning Center (JTWC) was established in 1959. The mission of JTWC is to provide analysis, forecast and decision support to enable DoD and other decision makers to plan, prepare, and protect against the threat of tropical cyclones, tsunamis and other weather impacts. This presentation will provide a brief history and overview of… Read more »
Effects of Midwinter Arctic Leads on Boundary Layer Clouds
February 7, 2019 1:30 pm
ATS West 121
Presented by: Steven Krueger
Hosted by: Dave Randall
Visiting from the University of Utah
Leads are quasi-linear openings within the interior of the polar ice pack, where the ocean is exposed directly to the atmosphere. Due to the extreme air-water temperature contrast (20 to 40 K), turbulent and radiative heat fluxes over leads can be two orders of magnitude larger than those over the ice surface in winter and… Read more »
Use of Trace Gas Measurements to Quantify Convective Transport Time Scales and Pathways
January 25, 2019 10:45 am
ATS room 101
Presented by: Z. Johnny Luo
Hosted by: Sue van den Heever
Visiting ATS from the City University of New York
Discussion will begin at 11:15 a.m. Refreshments will be served at 10:45 a.m. in the weather lab Convective transport from the marine boundary layer (MBL) to the upper troposphere (UT) is investigated using airborne in situ measurements of chemical species over the tropical western Pacific (TWP). Using 42 trace gas species with photochemical… Read more »
