Numerical models such as the Mesoscale Model 5 (MM5) or the Weather Research and Forecasting Model (WRF) are used by meteorologists in the prediction and the study of hurricanes. The outputs from such models vary greatly depending on the model, the initialization conditions, the simulation resolution and the computational resources available. The overwhelming amount of data that is generated ca...

Precipitation forecast verification is essential to the quality of a forecast. The Gaussian Mixture Model can be used to approximate the precipitation of several rain bands and provide a concise view of the data, which is especially useful for comparing forecast and observation data. The robustness of such comparison mainly depends on the consistency of and the correspondence between the extrac...

The article is devoted to meteorologists – Saratov State University staff of the Faculty Geography, who took part in meteorological support front during Great Patriotic War.

The forecast process within an operational weather centre is based upon the analysis, diagnosis and prognosis of skilled meteorologists. To aid their efforts, the forecasters use a wide range of tools including weather satellites, radar, workstations, and numerical weather prediction (NWP) models. Tremendous gains in NWP performance over the past 2 decades has made this tool typically the most ...

High resolution computational weather models are becoming increasing complex. However, the analysis of these models has not benefited from recent advancements in volume visualization. This case study applies the ideas and techniques from multi-dimensional transfer function based volume rendering to the multivariate weather simulations. The specific goal of identifying frontal zones is addressed...
