Impact of soil moisture updates on temperature forecasting

Ha, S., Sun, J.. (2024). Impact of soil moisture updates on temperature forecasting. Geophysical Research Letters, doi:https://doi.org/10.1029/2024GL110283

The impact of land variables on temperature forecasts in atmospheric cycling is often underestimated or overlooked. This oversight primarily occurs due to the abundance of meteorological measurements available for assimilation and partly be...

TAMS: A tracking, classifying, and variable-assigning algorithm for mesoscale convective systems in simulated and satellite-derived datasets

Ocasio, K. M. N., Moon, Z.. (2024). TAMS: A tracking, classifying, and variable-assigning algorithm for mesoscale convective systems in simulated and satellite-derived datasets. Geoscientific Model Development, doi:https://doi.org/10.5194/gmd-17-6035-2024

The Tracking Algorithm for Mesoscale Convective Systems (TAMS) is a tracking, classifying, and variable-assigning algorithm for mesoscale convective systems (MCSs). TAMS was initially developed to analyze MCSs over Africa and their relation...
