A known limitation of the observed and synthetic Fog Product

Let’s analyze the following loop of the synthetic fog product, generated from the 4-km NSSL WRF-ARW model: http://rammb.cira.colostate.edu/templates/loop_directory.asp?data_folder=training/visit/loops/10oct11_syn_fog/ In this color table, grey into light blue represents increasing confidence in liquid water clouds.  Our example from the 0000 UTC 10 … Continue reading

Synthetic Satellite Imagery in Temperature Forecasting

Synthetic satellite imagery can be useful in forecasting temperature.  This example from September 20-21, 2011 demonstrates the utility of synthetic imagery from the 4-km NSSL WRF-ARW model in forecasting the overnight low temperature. Focusing on southeast Wyoming, examine the synthetic … Continue reading
