Comparative Analysis of High-altitude Data Before and After Device Change in Xinjiang
摘要
Abstract
Using daily data of height,temperature,dew point temperature at 07 am and 07 pm at ten potential isobaric levels from 850hPa to 100hPa from the L-band and 59-701 system observations from the selected eight stations in Xinjiang including Altay,Aksu,Hotan,the analysis of value difference,degree of dispersion,t-test,and the revised equation establishment were conducted.The study foundinds are as follows.(1)When the 07 am temperature difference at the five stations including Altay,Korla,Minfeng is positive which indicates that L-band radar detection of temperature values are greater than that from 59-701 system observations while is negative at Hami,Ruoqiang and Aksu.The temperature difference is more stable at most of the stations at 19 pm than that at 07 am.(2) The differences of heights at 07 am and 07 pm are positive below 250 hPa from 0 to-10 and increases rapidly above 250 hPa.Generally,the maximum value of the difference.is at 100hPa altitude.(3) In general,the difference of the dew point temperature at 07 am and 07 pm are negative,and the difference at 07 am is greater than that at 07 pm.(4)Most of the station's observations of height and temperature can pass the inspection with the reliability,α=0.0 which means the observations of L-band and 59-701 radar sounding have no significant difference.Both of the dew point temperature do not pass through T-test and so the correction equation is given by calculating.关键词
