AVN MOS TEMPERATURE AND DEW POINT GUIDANCE

February 3, 2000



PREDICTANDS:

All predictands were taken from TDL's archive of the hourly METAR data. The daytime max and nighttime min temperatures are not explicitly observed and reported, but are inferred from hourly temperatures and max/min observations valid for 6-h periods.



PREDICTORS:

FINAL DEVELOPMENTAL SAMPLE:

TEST SAMPLES: The warm and cool season samples were divided into two parts to assess the quality of the new guidance, namely, a dependent sample used to develop test forecast equations, and an independent sample on which to evaluate the forecasts made by the test equations.

VERIFICATION RESULTS:

Detailed results may be seen on the TDL home page at: http://www.nws.noaa.gov/tdl/synop/results.htm
