Abstract: A conjugate-gradient variational blending technique, based on the method of direct minimization, has been developed and applied to the problem of initialization in a limited-area model in the summer monsoon region. The aim ...

Abstract: The current major expansion in observational capability of line National Weather Service is principally in the volume of asynchronous data rather than synchronous observations at the standard synoptic times. Hence, the ...

Abstract: A limited primitive equation model has been used to study the feasibility of four-dimensional data assimilation in the monsoon region and, further, to study the applicability of several assimilation techniques currently ...

Abstract: The problem of four-dimensional data assimilation in the tropics has been studied using a limited-area primitive equation model. Of prime concern is the relative importance of different update variables and their impact ...

Abstract: This paper presents observations of the finescale three-dimensional kinematic and thermodynamic structure of a long-lived mesoscale gravity wave that occurred on 14?15 February 1992 during the Storm-scale Operational and ...

Abstract: On 14 February 1992, a long-lived moderate-amplitude mesoscale gravity wave formed in Kansas during the Storm-scale Operational and Research Meteorology-Fronts Experiment Systems Test (STORM-FEST). Wave formation was evident ...

Abstract: A winter snowstorm developed on 10?11 February 1988 over the midwestern United States and produced several inches of snowfall locally over east-central Illinois. Analysis of the mesoscale organization of the storm revealed ...
