The task of Weather forecasting requires visualization of large data volumes. Numerical Weather Prediction models (NWP) are essential tools, and are typically run in batch systems for predetermined areas where data is available only at the end of each complete run . The NWPs are often run for as large an area as the available computer resources allow, this limits the resolution and area covered...

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 ...

Forecasts of precipitation and water vapor made by the Met Office global numerical weather prediction (NWP) model are evaluated using products from satellite observations by the Special Sensor Microwave Imager/Sounder (SSMIS) and Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis (TMPA) for June–September 2011, with a focus on tropical areas (308S–308N). Consistent...

The paper documents the development of a global nonhydrostatic finite-volume module designed to enhance an established spectral-transform based numerical weather prediction (NWP) model. The module adheres to NWP standards, with formulation of the governing equations based on the classical meteorological latitudelongitude spherical framework. In the horizontal, a bespoke unstructured mesh with f...

Observations from microwave sounding instruments have been exploited widely for numerical weather prediction (NWP) and for climate studies assessing long-term trends in atmospheric temperatures. Observations from channels in the 50-58 GHz range have been particularly valuable in providing information on tropospheric and stratospheric temperatures and are currently one of the most beneficial obs...

Simian foamy viruses (SFVs) co-evolved with a wide range of Old World and New World primates (OWPs and NWPs, respectively) and occasionally transmit to humans. Previous studies of OWPs showed that the predominant site of SFV replication is the oral mucosa. However, very little is known about SFV viral loads (VLs) in the oral mucosa or blood of NWPs. NWPs have smaller body sizes, limiting collec...

Numerical weather prediction (NWP) models have been widely used for wind resource assessment. Model runs with higher spatial resolution are generally more accurate, yet extremely computational expensive. An alternative approach is to use data generated by a low resolution NWP model, in conjunction with statistical methods. In order to analyze the accuracy and computational efficiency of differe...

Land surface processes and their initialization are of crucial importance to address the challenge of seamless (from weather to seasonal) Numerical Weather Prediction (NWP). In particular it has been found that soil moisture influences the landatmosphere exchange processes on all relevant time scales. It is therefore expected to be of high interest for NWP applications to assimilate new satelli...

SeaWinds data are provided by the Jet Propulsion Laboratory (JPL) at 25-km resolution, whereas most numerical weather prediction (NWP) models use observations at least a 100-km density. We have developed a QuikSCAT wind product at a coarser resolution than the JPL product in order to achieve a more appropriate information content for assimilation in NWP models. This product includes quality con...

Wind power prediction accuracy is important for assessing the security and economy when wind power is connected to the grid, and wind speed is the key factor. This article presents a future four hours prediction scheme that combined chaos phase space reconstruction with NWP method. Historical wind speed data are reconstructed as phase space vectors, which are used as the first input part of pre...
