Abstract

Aviation Weather Observations vs. LAMP Forecasts with the Onset of Precipitation BY DAVID E. RUDACK TABL E I. Definition of aviation flight categories. o the casual observer, precipitation events are as- sociated with reduced horizontal visibilities and/ Flight Visibility Tor lower cloud ceiling height.1 This agrees with Ceiling height (ft) category (miles) our experience that poor visibility and/or low ceiling heights are generally accompanied by a moisture-laden VLIFR < 200 and/or <0. 5 atmosphere. The astute observer would also notice occasions when horizontal visibilities improve and/ LIFR > 200 t o < 500 and/or 0.5- 1 or ceiling heights rise at the onset of precipitation for IFR > 500 t o < 1,000 and/or 1- 3 both trace and measurable precipitation events. Under- standing the relative frequency distribution of bot h the MVFR > 1,000 t o < 3,000 and/or 3- 5 lowering and rising of visibility and ceiling height in a window just prior to and shortly after precipitation VFR > 3,000 and > 5 begins is beneficial fro m a purely academic standpoint and crucial for generating accurate aviation forecasts in less tha n ideal weather conditions.
