Abstract

The identification of tropical cyclone (TC) formations in the Navy Operational Global Atmospheric Prediction System (NOGAPS) analysis and forecast fields, was discussed. The NOGAPS forecasts of TC formations in the western North Pacific (WNP) during 1997-1999 were verified. The number of false alarms (FA) in the NOGAPS forecasts was also examined, and it was identified that a large growth in FAs occurs between 24 h and 48 h before reaching a near saturation at later times. It was observed that NOGAPS can successfully handle formation cases in monsoon shear line with enhanced cross-equatrial flow.
