GOES-11 (GOES-West) visible channel images (above) displayed an unusually large area of open-cell cumulus clouds across the North Pacific Ocean on 20 January 2010. This type of open-cell mesoscale convective cloud pattern is a signature of strong instability (via boundary layer cold air advection over relatively warmer waters) in an environment of... Read More

McIDAS images of the 4-km resolution GOES-11 10.7 µm IR channel data (above) showed the development of convection that moved onshore across southern California during the afternoon hours on 19 January 2010. Of particular interest is the strong convective cluster that developed just offshore over the Santa Catalina and San Clemente Island... Read More

An AWIPS image of the 1-km resolution POES AVHRR 11.0-3.7 µm “fog/stratus product” (above) revealed a very interesting banded structure in the fog and stratus features (yellow to red color enhancement) that covered a large part of the western Great Lakes region at 07:49 UTC on 16 January 2010. With stagnant high... Read More
