Vertical wind shear is the change of wind speed and/or direction with height. For tropical cyclones, wind shear is something that must be overcome if strengthening is to occur. For (minimal) tropical storm Danny, strong wind shear has persisted in keeping convection far from the storm center. When the storm... Read More
An area of disturbed weather north of the Bahamas developed into Tropical Storm Danny early on 26 August. Satellite loops of the visible imagery, above, clearly show a low-level circulation that is displaced from the area of main convection to the north and east. Until the convection and the low-level...

GOES-14, which was launched on 27 June and is now undergoing post-launch check-out, is over the Equator at 90 degrees W longitude, whereas GOES-12, the operational GOES-East, is over the Equator at 75 W Longitude. The two satellites give slightly different views of Hurricane Bill, and stereoscopy can be used to view the visible imagery, allowing... Read More
Super Rapid Scan Operations are called on GOES-East or GOES-West when meteorologists want to investigate phenomena that occur over very short timescales. Typically, SRSO imagery is taken every minute. However, gaps exist because of responsibilities to other regions. For example, when the National Hurricane Center requested SRSO observations of Hurricane... Read More
