Nimrod

Nimrod is a fully automated system for weather analysis and nowcasting based around a network of C-band rainfall radars.

It provides fine-resolution analyses and six-hour forecasts to forecasters and to Met Office customers direct.

Nimrod delivers routine predictions of:

• Rainfall rate
  
• Rain accumulation
  
• Precipitation type
  
• Snow probability
  
• Cloud
  
• Visibility
• Wind gust speeds

The value of radar-based data from the Nimrod system has been highlighted repeatedly. For example, in two severe flooding events during 1998 (at Easter over the Midlands and in late October over Wales), estimates of surface rainfall derived from radar data provided evidence of the extent and severity of the rainfall events.

Recent additions and improvements cover the visibility forecast and the introduction of an improved lightning prediction scheme, including extrapolation of recent strike locations, and improvements in the ways of predicting rime accumulation.
