30 May 2005/06.00 UTC - Airmass Analysis
The Air Mass Analysis product of the SAFNWC aims to support the nowcasting applications through providing several products describing air mass characteristics. These characteristics are determined by the surface temperature, the moisture content of the airmass and the stability of the airmass derived from SAI (Stability Analysis Index). The criteria then allow a discrimination of about 16 different airmasses Because of the use of the surface temperature the AMA can only be calculated for cloudfree areas.
Most of Eastern Europe is reflected as tropical continental airmass. A more closer look also reveals some maritime airmasses. Striking however is that the airmasses identified, are indicated as being stable.
