Comparison of the dynamics of a land vs. oceanic explosive cyclone.
Two explosively developing cyclones are analyzed and compared using a similar diagnostic approach. A continental cyclone developed over the U.S. Midwest during 14-17 November 1988 and was analyzed using NMC Nested Grid model analysis fields and GOES IR imagery. A maritime cyclone rapidly developed o...

Two explosively developing cyclones are analyzed and compared using a similar diagnostic approach.
