The National Weather Service forecast office on Guam (where the National Weather Service day begins!) has a very large Area Of Responsibility (AOR), as shown in this image; it stretches from the Equator northward to 25oN, and from the dateline west to 130oE. At ca. 1800 UTC on 1 April 2024 (no foolin’!) the... Read More
LightningCast is a product within the ProbSevere portfolio that uses 4 ABI (or AHI) channels to estimate the likelihood of a GLM observation within the next 60 minutes. For the past couple years, this product has been used experimentally over Guam (using Himawari-9 data), even though the product was trained using... Read More
CSPPGeo software to create LightningCast probability fields is in (pre-Beta stage) testing at CIMSS (as noted in this recent blog post). In addition to creating output using GOES-R data, the software will also create imagery from Himawari-9 data. There is a RealEarth instance for LightningCast probability that includes a small Guam sector cut-out, but the CSPPGeo... Read More
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
