MRF MOS TEMPERATURE AND DEW POINT DEVELOPMENT

February 3, 2000



Predictand Definition

The predictands for the MRF-based MOS max/min guidance were values corresponding to a local daytime maximum and nighttime minimum temperature. The daytime is defined as 7 AM to 7 PM Local Standard Time (LST); nighttime from 7 PM to 8 AM LST. An algorithm is used to calculate max/min from METAR observations. The predictands for the 6-h temperature and dew point guidance were observations reported at specific times each day. Predictands are valid at projections 18 to 192 hours from after model run time (00 UTC).
