中文摘要: 选取山东有代表性的5个台站2005年9个月的自动站资料进行统计,得出其主要气象要素日 极值在各时间点上的分布情况。结合每一要素的校准时间长度和台站的发报时次及内容,对 各气象要素的校准时段进行了分析。结果表明,各气象要素最佳校准时段:湿度为8—10时 ,浅层地温为14—17时30分,深层地温为8—11时30分,风向风速为8—9时30分或16时30分 —18时,气压为11—12时30分,蒸发为8—8时30分或17时30分—18时。据此合理安排自动站 现场校准时各气象要素的校准时间和次序,可使校准工作对自动站
Abstract:On the basis of the 9 month observational data from five representative AWS in 2005, daily extremum distributions of main meteorological elements were obtained by the statistical method. Calibration period of various meteorological element s is studied by analyzing calibration time span and data transmitting schedule. The results show that the optimal calibration period of various meteorological e lements is as follows: humidity:8:00-11:00, fleet soil temperature:14:00-17:30, deep seated soil temperature:8:00-11:30, wind direction and wind speed:8:00 -9:3 0 or 16:30-18:00, barometric pressure:11:00-12:30,evaporation:8:00-8:30 or 17:30 -18:00. These results will help to revise the schedule of on the spot calibra tion of AWS, and reduce the influence of calibration operation on AWS observatio n.
