The use of big data in weather forecasting is examined this article. Large and complicated collections that can be to find patterns, trends, relationships are referred as "big data." Big has become more crucial recent years since it offer insightful information about trends boost precision. difficulties using large for discussed the article along with methods processing analyzing it. It also of...

A fundamental function of any aviation weather system is to provide accurate and timely weather information tailored to the specific air traffic situations for which a system is designed. Weather location and intensity are of prime importance to such systems. Knowledge of the weather provides “nowcasting” functionality in the terminal and en route air spaces. It also is used as input into aviat...

High-resolution synthetic aperture radar (SAR) wind observations provide fine structural information for tropical cycles and could be assimilated into numerical weather prediction (NWP) models. However, in the conventional method assimilating the u and v components for SAR wind observations (SAR_uv), the wind direction is not a state vector and its observational error is not considered during t...

In this paper we describe the implementation of a numerical weather forecast model on a massively parallel computer system. This model is a production code used for routine weather forecasting at the meteorological institutes of several European countries. The modi cations needed to achieve a data-parallel version of this model without explicit message passing are outlined. The achieved perform...
