Dear all,

Please join us this Thursday February 23 for a Meteorology seminar, given by Dr. Rosimar Rios-Berrios of NCAR. Dr. Rios-Berrios will speak about “Tropical Weather Systems in a Hierarchy of MPAS-A Aquaplanet Simulations” (abstract below).

Dr. Rios-Berrios will be joining us IN PERSON. Please join us in EOA 1044 at 3 PM for refreshments prior to to the beginning of the talk at 3:15 PM.

Graduate students are invited to join a student-only lunch with the speaker at 12:30 PM. This is a great opportunity to meet the speaker in a casual setting - and have some free food :-) Please RSVP to Allison Wing (awing at fsu.edu<mailto:awing at fsu.edu>) by the end of the day Wednesday.

Dr. Rios-Berriosl is also available for individual meetings on Thursday. If you’d like to meet with her, please contact Allison Wing (awing at fsu.edu<mailto:awing at fsu.edu>).

We look forward to seeing you all on Thursday!

DATE: Thursday February 23
SEMINAR TIME: Refreshments at 3 PM, Talk 3:15 PM - 4:15 PM.
SEMINAR LOCATION: EOA 1044
SPEAKER: Dr. Rosimar Rios-Berrios

TITLE: Tropical Weather Systems in a Hierarchy of MPAS-A Aquaplanet Simulations

ABSTRACT: Tropical weather systems are important components of Earth’s climate system—from being key players in redistributing heat and moisture from the tropics to the high latitudes to manifesting into powerful high-impact phenomena (e.g., hurricanes). Despite being so important, the representation of tropical weather systems and their variability is deficient in most climate and weather prediction models. This study tackles this issue by examining the multi-scale variability of tropical weather systems in a hierarchy of idealized model experiments with varying horizontal cell spacing—from 120 km to 3 km. All experiments were produced with the Model for Prediction Across Scales-Atmosphere (MPAS-A). In the first part of this talk, I will introduce a set of MPAS-A aquaplanet experiments and will demonstrate that all experiments capture tropical rainfall variability driven by equatorial waves. In the second part, I will present a novel analysis of the structure of convectively coupled equatorial waves as represented in both aquaplanet and real-data experiments. This analysis shows that convection-permitting resolution captures a more accurate vertical structure due to a better representation of diabatic heating within the equatorial waves. This, in turn, affects the rainfall intensity and evolution of the simulated waves. I will conclude with a discussion of the implications of these results, along with examples of other science topics that could be explored with the MPAS-A aquaplanet experiments.

We look forward to seeing you there!

Cheers,

Allison
