As a strong arctic cold front moved southward across the Gulf of Mexico and southern Mexico (surface analyses) on 12 March 2022, the cold air passed through the Chivela Pass and emerged as a Tehuano (or “Tehuantepecer“) gap wind that fanned outward across the Gulf of Tehuantepec. Visible images from GOES-17... Read More
Turbulence probability is an aviation tool created (using machine learning techniques) at CIMSS to diagnose the likelihood of Moderate Or Greater (MOG) turbulence at least once during a 10-minute period. The image above shows the 1455 UTC MOG Turbulence Probability along with pilot reports (PIREPS) of turbulence, taken from this website.... Read More
In addition to its use in detecting wind fields over water (link 1, link 2), SAR data can also be used to detect ice. An example is shown above: similar domains on 20 and 24 January 2022 (from this website; this image on 20 January 2022 and this on one 24 January 2022) are toggled. There is a general increase in Lake Michigan shore... Read More
1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) displayed mesovortices over southern Lake Michigan on 21 January 2022. The formation of these mesovortex features was aided by a mid-lake convergence of surface winds, which was suggested by RAP40 surface wind fields and shown n more detail by Metop-C ASCAT...
