Study On Correlation Analysis And Preventive Measures Of Hail Disaster In Akesu

Although the scale of the hail is relatively small,the duration of the hail is relatively short,but the arrival is very sudden and destructive,which is a meteorological disaster caused by extreme convective weather.Severe convective weather causes hailstones and causes many disasters,and the occurrence of hailstones often leads to sudden disasters such as high winds,high intensity precipitation,and rapid temperature drops.There are many hailstones in xinjiang,which can cause serious damage to agriculture,construction,power facilities and people's life and property safety in the region every year.Therefore,it is necessary for us to carry out in-depth research on the prediction and early warning of hail disaster,so as to improve the prevention and control measures of hail disaster,so as to reduce the economic loss.Because of the special geographical location and climatic characteristics of aksu region,it is often affected by extreme weather.At present,most meteorological units use doppler radar to monitor and forecast extreme weather.By means of the traditional correlation analysis method,this paper selected the various indicators and hail area per month,season and year correlation coefficient calculation,three groups of related coefficient,as falling hail area is the basis of the factors affecting the discriminant,secondly with statistical significance correlation coefficient method(Pearson correlation coefficient)of the temperature,precipitation,sunshine hours and hail area after data preprocessing the correlation coefficient between them was calculated,and statistical test to do a hypothesis test,finally through the inspection determine the temperature,precipitation and sunshine duration in which the effect of factors on the hail area reduction is large,The new anti-hail measures and countermeasures were put forward after the main factors were found out,and some contribution to the anti-hail work in the region was made to reduce the economic losses.The article also applies the classification method,the statistical method and the summary method to make and verify the influence factors of hail area.This article includes five parts.First,the research status,research contents and research methods of the background,research significance and prediction and early warning of hail disaster prediction are described.Second,the overall situation of aksu prefecture;Third,spatial and temporal distribution of hail disaster in aksu area is analyzed.Fourth,the traditional correlation analysis;Finally,the correlation analysis and summary of statistical significance.
