I worked with Dr. Daniel Chavas, during my senior year at Purdue University, on analyzing the relationship between initial mid-tropospheric moisture and tropical cyclone size during landfall. Data from the GFDL HiRAM C180 and GFDL Hurricane Model were used to determine if a relationship between radially averaged profiles of 500-hPa relative humidity and azimuthal wind exist. The relationship between initial mid-tropospheric moisture and initial tropical cyclone size, varied greatly case-by-case, but no significant relationship arose.
I worked with Dr. Yutian Wu, during my junior year at Purdue University, on examining the atmospheric response to arctic amplification. Data from the GFDL-CM3 500-year preindustrial run was used in order to understand the changes of the atmosphere’s physics and dynamics during anomalously warm years without the influence of external human interaction. Results showed decreases of mid-latitude surface air temperature, an equator-ward shift of the thermally driven jet, and an increase in mid-latitude precipitation; supporting proposed theories that a decrease in the equator-to-pole temperature gradient results in more frequent “wavy” patterns of the jet stream and a resultant increased frequency of mid-latitude extreme weather.
