MIMIC TPW – Meridional Wind Imagery:
Background:
This imagery is created by combining the MIMIC total precipitable water (TPW)
product over water and the GOES-16 10.3 µm and Meteosat 10.8 µm IR
longwave bands over land. Meridional wind contours derived from UW-CIMSS gridded
atmospheric motion vector (AMV) files are overlaid on the images and include
“low-level” (850-925 hPa) and a “mid-level” (600-700 hPa) analyses.
Uses:
This merged image is useful for tracking African easterly waves (AEWS), tropical
disturbances, and large scale atmospheric features.
Notes:
• Images with low-level meridional winds are useful for tracking features
such as tropical disturbances and low-level jets.
• Images with mid-level meridional winds are useful for tracking features
such as AEWs.
