SWEAT Index

SWEAT Index - Severe Weather ThrEAT index. A stability index developed by the Air Force which incorporates instability, wind shear, and wind speeds as follows: SWEAT = (12 Td 850 ) + (20 [TT-49]) +( 2 f 850) + f 500 + (125 [s+0.2]) where ...


The SWEAT Index and Total-Totals Index The SWEAT Index was derived by the Air Force, not for putting cadets through basic training but for indicating the potential for severe weather to pilots.

The SWEAT index has the advantage (and disadvantage) of using only mandatory-level data (i.e., 500 mb and 850 mb), but has fallen into relative disuse with the advent of more detailed upper air sounding analysis programs.SwellWind-generated waves that have travelled out of their generating area.

Severe WEAther Threat Index (SWEAT Index): A stability index developed by the Air Force which incorporates instability, wind shear, and wind speeds.
