Visible imagery over Hurricane Milton after sunrise on 7 October, above, shows a compact system about 100 miles northwest of the Yucatan Peninsula. The predicted track of the storm center is superimposed on the imagery. Note that Milton’s sustained winds at 1500 UTC, 135 knots, represents an 80-knot increase over... Read More
As first hinted at in this blog post, the Community Satellite Processing Package for Geostationary Data (CSPP-Geo) (https://cimss.ssec.wisc.edu/csppgeo/ ) group at CIMSS has released a beta version of a unix-based package that computes LightningCast probabilities. LightningCast (available online in real time for select regions) diagnoses the probability of a Geostationary Lightning Mapper (GLM) observation of lightning within... Read More
GOES-16 Visible imagery (Band 2, 0.64 µm) from Mesoscale Sector 1, above, show the evolution of Helene for about 90 minutes shortly after sunrise on 26 September. Strong convection is wrapping around a center that occasionally has an eye-like characteristic. At the time of the animation, Helene was a very... Read More
GOES-18 True-Color imagery, above, from the CSPP Geosphere website (link to animation above), shows convection moving over northeastern Wyoming, leaving in its wake a series of smoke plumes: wildfires caused by lightning. The screenshots below were captured from the Real Earth instance of NGFS imagery (link), and they show LightningCast probability and Flash... Read More
