Mid-level jet in intense convective environment as seen in the 7.3 µm satellite imagery

Images in the 7.3 µm and 6.2 µm channels are used to detect coupling between low- and mid-level conditions dynamics associated with intense convective developments. As a tool for water vapour imagery analysis in diagnosing this context, “dynamic wind shift”−defined as difference in the position of mid- and upper-level jets over a short distance, seen in the WV images−is considered. Two types of intense convective developments over the Mediterranean are distinguished, associated with “smooth” and “sharp” dynamic wind shift conditions, upstream of the zone of intense convection.
