[Eoas-seminar] MET Seminar - This Thursday April 6 - Dr. Alyssa Stansfield (Colorado State University)

Mon Apr 3 12:00:40 EDT 2023

Dear all,

I’m not sure why the formatting of the abstract was so weird. Here is another attempt:

TITLE: How and Why Does Tropical Cyclone Precipitation Respond to Climate Change?

ABSTRACT:

Tropical cyclone (TC) precipitation can create dangerous hazards and cause millions of dollars in damages. While previous literature agrees that future TC precipitation will increase due to rising global temperatures, the estimates of how much it will increase vary, ranging from around 3 to 20% per °C of warming, or three times the Clausius-Clapeyron scaling (about 7% per °C). In this talk, various methodologies and datasets are utilized to disentangle the interwoven factors that impact the response of TC precipitation to warming, including TC intensity, outer size, landfall frequency, and increases in atmospheric moisture. Results are first presented for the North Atlantic and eastern United States specifically and then generalized globally using idealized aquaplanet model simulations. The idealized simulations are compared to more realistic global model simulations and satellite observations of TC precipitation. Finally, proposed high-resolution (~1 km) limited-domain idealized simulations with the goal of exploring changes in three-dimensional TC precipitation structures as sea surface temperatures warm are discussed.

Dear all,

Please join us this Thursday April 6 for a Meteorology seminar, given by Dr. Alyssa Stansfield from Colorado State University. Dr. Stansfield will speak about “How and Why Does Tropical Cyclone Precipitation Respond to Climate Change?" (abstract below).

Dr. Stansfield will be joining us virtually but we will gather in EOA 1044 to participate in the seminar. If you cannot attend in person due to a medical reason or approved work out of town, please contact Allison Wing (awing at fsu.edu<mailto:awing at fsu.edu>) for remote access. Otherwise, we look forward to seeing everyone in 1044! Please join us for refreshments prior to the beginning of the talk at 3:15 PM.

If you are interested in meeting with the speaker, please contact Allison Wing. She is available for virtual meetings between 11 AM and 3 PM.

DATE: Thursday April 6
SEMINAR TIME: Refreshments at 3 PM, Talk 3:15 PM - 4:15 PM.
SEMINAR LOCATION: EOA 1044 (Speaker remote)
