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 GOES-12 and GOES-14 visible channel data (above) showed that large chunks of ice (known as “ice fields”) were drifting north-northeastward across the western portion of Lake Erie on 14 January 2010. Southerly to southwesterly winds were beginning to increase on that day, helping to move the ice features across... Read More
