An important field of weather observation is the statement of cloud cover of the sky. Clouds not only are significant for the daily weather forecast but also are important for energetic calculations of atmospheric

The long-term goal of this project is to improve the prediction of tropical cyclone (TC) genesis, structure and intensity changes through improved representation of 3-dimensional TC structure at the initial time. The accurate prediction of TC genesis, structure and intensity changes is critical to Navy missions and civilian activities in coastal areas. Significant gains have been made in the TC...

This paper reports experiments in which pCRU — a generation framework that combines probabilistic generation methodology with a comprehensive model of the generation space — is used to semi-automatically create several versions of a weather forecast text generator. The generators are evaluated in terms of output quality, development time and computational efficiency against (i) human forecaster...

Applying 4-levels grid nested WRF (Weather Research and Forecasting) model to predict meteorological elements of wind farm field, and employing WRF model outputs and SCADA data of wind turbines to construct wind power forecast models by using the APLSR (Adapting Partial Least Square Regression) method, this paper has conducted wind power forecast in 24 hours ahead, at Wenling wind farm which lo...

Weather forecasts are nearly always portrayed from either a satellite view perspective, a numerical or symbol based representation. None of these methods actually portray weather visually from the point of view of the observer, that is, they do not represent our experience of weather. This problem presents a challenge to displaying weather using real-time 3D computer graphics. 3D Weather is a p...

FEBRUARY 2004 AMERICAN METEOROLOGICAL SOCIETY | S cientific research on atmospheric processes and weather forecasting frequently leads to improvements in weather forecasts [such as quantitative precipitation forecasts (QPF)], as measured by scientific criteria. Furthermore, effective use of such improvements has the potential for avoiding injury and death, averting property and environmental da...

MIT Lincoln Laboratory has developed the Route Availability Planning Tool (RAPT), which provides automated convective weather guidance to air traffic managers of the NYC metro region. Prior studies of RAPT have shown high-accuracy guidance from forecast weather, but further refinements to prevent forecast misclassification is still desirable. An attribute set of highly correlated predictors for...

An enhanced version of the hybrid ensemble–three-dimensional variational data assimilation (3DVAR) system for the Weather Research and Forecasting Model (WRF) is applied to the assimilation of radial velocity (Vr) data from two coastal Weather Surveillance Radar-1988 Doppler (WSR-88D) radars for the prediction of Hurricane Ike (2008) before and during its landfall. In this hybrid system, flow-d...

Acoustic rain gauges have long been espoused as a possible means of monitoring wind and rainfall in regions far from land-based measurements. The rapid provision of data from such systems could contribute to weather forecasting. This paper provides an overview of a recent equipment trial off Galway, during which wind speeds in excess of 30m s -1 were encountered. The deployment also tested the ...
