Observational Analysis And Modeling Of The "B" Regional Dust Storm On Mars, Courtney Marylou Batterson May 2021

Observational Analysis And Modeling Of The "B" Regional Dust Storm On Mars, Courtney Marylou Batterson

Master's Theses

The annually-recurring, regional B storm on Mars occurs at the highest southernlatitudes in years lacking a global dust storm (GDS), and produces warm temperatures (> 200 K) at 50 Pa over the south pole. Observations of the B storm are limited due to the lack of in-situ data in the polar regions of Mars, and reproducing polar phenomena using traditional latitude-longitude grid models is difficult because of the increasingly small grid spacing at the poles. The development of the new NASA Ames Mars Global Climate Model (MGCM), which has a finite-volume dynamical core, a uniform cubed-sphere grid, and several of …
