Offshore Marine Weather:
Weather conditions affect many offshore marine operations such as survey, exploration and other activities such as construction, production etc.
Weather forecasts are of immense importance in case of saving the human life from natural disasters. They also help reducing the economic loss. The biggest advantage of Doppler radar is to predict the velocity with which precipitation particles are moving towards or away from the radar and this helps for accurate weather forecasts.
