Synthetic Aperture Radar (SAR) winds from RCM1 (RADARSAT Constellation Mission 1) over the south Pacific Ocean, from this site, show a gradient in wind speeds between 165 W and 168 W. Are there other ways to view this type of wind change over the open ocean?GOES-17 Derived Motion wind vectors, below,... Read More

This past CIMSS Blog Post showed a region of very strong bowing winds diagnosed by Synthetic Aperture Radar (SAR) data and associated with a convective complex over Lake Superior before sunset on 25 May 2021.   On 3 June 2021, shortly after sunrise (SAR overpasses over the Great Lakes typically occur around 0000 and 1200...

GOES-16 visible imagery, above, shows a line of convection moving over Lake Superior late in the day on 25 May 2021. Merged MRMS Radar Reflectivity at 2340 UTC, below, (from this website) shows radar echoes approaching 45 dBz (at a fair distance from the radars being used to produce the imagery). What... Read More

The toggle above shows GOES-17 ABI Band 2 (“Red Visible” at 0.64 µm) and Band 5 (“Snow/Ice” at 1.61 µm) imagery at 1740 UTC on 8 April 2021. 60ºN and 170ºW lat/lon lines are included in yellow, as well as Nunivak Island.  There is evidence of sea ice extending from south of... Read More
