WEATHER PREDICTION
Weather Prediction is the process (science, art) by which the future state
of the atmosphere is determined from current weather patterns using
various methods.
The problem of determining a physically consistent and accurate
snapshot of the atmosphere is the central aim of the numerical weather
prediction (NWP). In last few decades, with progress in both computing
power and optimisation strategies, more sophisticated constraints and
diverse observations have been included in NWP. The weather
prediction puts a heavy demand on strong 3-dimentional database
requiring a dense network of observations from ground as well as
satellite platforms.
