LightningCast probability fields are routinely produced at CIMSS and incorporated into a RealEarth display (LightningCast probability fields are also available in some National Weather Service AWIPS machines). An example of LightningCast is shown below over Southern Florida. Contours show the probability of a GLM observation of lightning within the next 60 minutes:... Read More
Upper-level water vapor imagery, above, shows the development of standing waves in the lee of the Hawai’ian islands. (The waves were also apparent in mid-level and low-level water vapor imagery). Wave development as shown above requires a perturbation in the vertical — achieved by southwesterly flow in the atmosphere encountering... Read More
The toggle of true-color MODIS imagery above, (taken from the MODIS Today website) shows Terra MODIS imagery on 14 and 15 January 2024. The 14th was the first day of an Arctic outbreak over deep snowcover in the upper Midwest; Madison WI was at/below zero the entire day. As a consequence, many lakes that were open water on...

Upper-air rawinsondes at station 74455 (Davenport, Iowa, above) show the response at that point to the approach and development of a potent winter storm (See the Airmass RGB animation below). The lowest levels of the atmosphere have saturated in the 12 hours between upper air observations. Model soundings, after the... Read More
