An Evaluation of the Navy Atmospheric Boundary Layer Model

Abstract

The results from a test performed to validate the Navy Atmospheric Boundary Layer (NABL) model are presented. Average statistics indicate that NABL forecast temperature profiles compare favorably with those from a 40 km horizontal resolution version of the Navy Operational Regional Atmospheric Prediction System (NORAPS), but that negative (dry) moisture biases are more severe in the NABL model. Test results indicate that the NABL model is superior to NORAPS for short-range forecasting of elevated trapping layers; however, NABL's ability in surface ducting assessment was found to be limited. It is recommended that the NABL model be upgraded to operational status so that its use in refractivity forecasting and in applications programs which profile high resolution boundary layer information may be exploited.
