abstract long-term historical weather data are needed to conduct crop simulation analysis. simulated climatic data may be used when long series of historic data are not available or convenient or when future data are needed. the aim of this study was to generate daily weather values for maximum and minimum air temperatures. a number of weather generators are compared here. data from ten station...

This paper proposes and implements a statistical methodology for adjusting employment data for the effects of deviations in weather from seasonal norms. This is distinct from seasonal adjustment, which controls only for the normal variation in weather across the year. We simultaneously control for both of these effects by integrating a weather adjustment step in the seasonal adjustment process....

The United States Government assumes no liability for its contents or use thereof. Providing an accurate picture of the weather conditions in the pilot's area ofinterest is a highly useful application for ground-ta-air datalinks. The problem with using data links to t...

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 research the daily data of 69 climatic variables (wind direction, wind speed, dry temperature, wet temperature, maximum and minimum temperature, average daily temperature, precipitation, relative humidity, station level pressure, cloudiness, horizontal visibility, vapor pressure, …) of abumoosa synoptic station during the years 1362-1388 were studied. initially, a data base of variabl...
