摘要
降水现象是天气现象的重要组成部分,是气象站观测的重要项目之一,我国《地面气象观测规范》规定的台站观测项目为降水量、降水时数、降水强度以及降水类型。降水类型的自动识别仪器在我国还没有实现业务化,只在某些研究领域使用。本文介绍了基于光学原理的降水类型自动识别技术的发展现状以及各种识别技术的原理、特点和不足,并展望了其未来的发展趋势。
Precipitation is an important part of present weather,which is one of the significient items for weather station observation.The observation items in the Specification of Surface Weather Observations include precipitation amount,precipitation duration, precipitation intensity and precipitation type.However,the automatic recognition for precipitation type has not realized in China,which is only used in certain research areas.This article presents automatic recognition precipitation based on optical principle, and analyses the principle, feature and shortage of each kind of technologies. At last, the outlook for the future development is proposed.
