Validating NASA’s IMERG Rainfall analysis with Florida Automated Weather Network Observations (FAWN)
By Cameron Matthis
Description: IMERG is a widely used gridded global dataset, while FAWN is a high-resolution in-situ dataset specific to Florida. Given IMERG’s extensive use, it is crucial to validate its rainfall analysis using ground-based observations like FAWN. In this study, I will assess IMERG and FAWN data across multiple temporal scales, including the time mean, seasonal, interannual, and diurnal timescales, to evaluate their strengths and weaknesses

Drivers of Summer  Mixed-Layer Cooling in the Northwestern Arabian Sea
By Ethan Wright
Description: The northwestern Arabian sea experiences large scale mixed-layer cooling on average throughout the summer months of June, July and August. Global HYCOM output is used to analyze the seasonal development and drivers of this cooling. A mixed-layer heat budget analysis at the model grid cell level is used to analyze the dominant space-and-time patterns of summer cooling with emphasis placed on contrasting the mesoscale and large-scale processes that affect the summer cooling off the coast of Oman.

Recent Changes in Moisture Flux Patterns over India: Implications for ISMR
By Amarjeet Vidyarthi
Description: Pure rotational and divergent components of moisture flux are computed and analyzed to investigate the recent changes in moisture flux patterns over India. This study is using the ERA-5 datasets. Our study finds that the rotational component of the moisture flux, which relates to moisture transport is strengthened in recent decades. This is attributed to the non-uniform rate of change of tropospheric air temperature in the lower and middle troposphere from the rising land-ocean thermal contrast. The rising trend in temperature is related to concomitant increase in the precipitable water content (PWC) over the Indian landmass especially in the middle troposphere. Moreover, the relatively higher warming in the middle troposphere results in stabilizing the atmosphere. Therefore, we also observe an increase in the fraction of stratiform precipitation in recent period resulting in increased mid-atmospheric diabatic heating which enhances the mid-tropospheric southwesterly moisture flux, in the recent decades.
