Abstract: Prefrontal squall lines are mesoscale convective systems that often cannot be linked to any preexisting organizing mechanism. This suggests the possibility that they are manifestations of a mesoscale instability involving ...

Abstract: An application of optimum interpolation (OI) is described for quality control and combination of wind profiler data with other observations of wind profiles. Data from three separate wind sensors at the National Aeronautics ...

Abstract: The performance of several schemes for diagnosing cloud cover from forecast model output was tested using a global numerical weather prediction model and the operational USAF RTNEPH (real-time nephanalysis) cloud analysis. ...

Abstract: A feature-based statistical method is investigated as a method of generating pseudoensembles of numerical weather prediction forecasts. The goal is to enhance or dress a single dynamical forecast or an ensemble of dynamical ...

Abstract: Retrieving information from remotely sensed data and analyzing the resulting geophysical parameters on a regular grid may be combined using a variational analysis method. This approach is applicable to the problem of ...

Abstract: This paper describes a cloud forecast technique using lag cross correlations. Cloud motion vectors are retrieved at a subset of points through multiple applications of a cross-correlation analysis. An area in the first of ...

Abstract: The inference of profiles of relative humidity from cloud data was investigated in a collocation study of 3DNEPH and radiosonde data over North America. Regression equations were developed for the first two EOFs of relative ...

Abstract: 31-yr time series of boundary layer winds has been developed for a region on the outer continental shelf. This simulated time series was designed to be suitable to study the wind resources for a potential offshore wind ...

Abstract: Prompted by the need for forecasts of changes in the length of day on 1-10 day time scales, this paper examines the quality of predictions of a proxy variable, namely the atmosphere's relative angular momentum (M) made by ...
