These datasets are useful in site suitability studies, fire management and many other fields where the prevaling weather is an important factor in modeling.įor most of the meteorological purposes, wind data is measured in terms of its orthogonal components i.e U (East-West) and V (North-South) components of the Wind. GIS toos provide a lot more features and tools to process and analyse wind data. Hence GIS softwares are not widely used or preferred by Met departments for processing the wind data.

Meteorological departments generally prefer softwares for time series analysis (to compare historical data) such as GrADS. These data are generally very difficult to process without the help of some software, which is generally the case for most meteorological departments all over the world.
Wind data is mostly available in a gridded format with values of X, Y accompanied by wind vector data. Wind being one of the main components of weather is difficult to acquire for a particular region let alone the whole world. Wind satisfies the conditions of vector quantity as it has both magnitude and direction, which varies according to the location, season and also the altitude. This wind parameter and its pattern determine most of the significant weather phenomena that occur around the world everyday from small wind gusts to the setting of monsoon. Meteorological conditions of any location at a given time are a function of many variables such as atmospheric temperature, relative humidity, pressure and mainly the wind parameter.
