Assessment/Forecasting of Anomalous Microwave Propagation in the Troposphere Using Model Output
Abstract
A method for forecasting microwave propagation conditions below the 850 mb level is described and evaluated using radiosonde data in the eastern North Pacific Ocean. The method demonstrates good skill in assessing the existence of ducting or normal propagation conditions below the 850 mb level. Duct altitudes are not provided in the assessment, nor are the probabilities of occurrence. The categorical assessment is based on an 850 mb parameter derivable from model output fields, and can be used in ocean regions characterized by a marine inversion below the 850 mb level. The method does not seem useful in ocean regions at high latitudes or in those characterized by warm surface currents.
