short range precipitation forecasts evaluation of wrf model over iran
iran has a complex topography and it consists of rugged, mountainous rims surrounding high interior basins. because of this condition, in some cases the nwp output has a significant error from mesoscale variations induced by the diverse topography. iran, covering an area of about 1,648,000 km2, is located in the southwest of asia approximately between 25° and 40° n and 44° and 64° e. this is p...
متن کاملThe Dependence of Short-range Ocean Forecasts on Satellite Altimetry
Short-range ocean forecast and reanalysis systems routinely combine observations from satellite altimetry, satellite sea surface temperature (SST), and in situ temperature and salinity, to initialise global and regional ocean models. The most critical observation type for eddy-resolving applications is arguably satellite altimetry. To quantify the impact of satellite altimetry observations on a...
متن کاملClustering Methods for Statistical Downscaling in Short-Range Weather Forecasts
In this paper an application of clustering algorithms for statistical downscaling in short-range weather forecasts is presented. The advantages of this technique compared with standard nearest-neighbors analog methods are described both in terms of computational efficiency and forecast skill. Some validation results of daily precipitation and maximum wind speed operative downscaling (lead time ...
متن کاملEvaluation of Temporal and Spatial Distribution of Tamdar Data in Short-range Mesoscale Forecasts
Upper-air observations are disproportionately sparse, both temporally and geographically, when compared to surface observations. The lack of data is likely one of the largest limiting factors in numerical weather prediction. Atmospheric measurements performed by the Tropospheric Airborne Meteorological Data Reporting (TAMDAR) sensor of humidity, pressure, temperature, winds aloft, icing, and tu...
متن کاملShort Range and Long Range Dependence
In this section a discussion of the evolution of a notion of strong mixing as a measure of short range dependence and with additional restrictions a sufficient condition for a central limit theorem, is given. In the next section I will give a characterization of strong mixing for stationary Gaussian sequences. In Sect. 3 I will give a discussion of processes subordinated to Gaussian processes a...
