Integrated meteorological observation environment simulation device

Abstract

The invention discloses an integrated meteorological observation environment simulation device. The device includes a semi-closed sunshade, rainfall simulators, a first controller, snowfall simulators, a second controller, refrigerators, drizzle simulators, a third controller, a hail simulator, a fourth controller, a regulator, a remote test platform and image collection units, wherein the rainfall simulators, the first controller, the snowfall simulators, the second controller, the refrigerators, the drizzle simulators, the third controller, the hail simulator, the fourth controller, the regulator, the remote test platform and the image collection units are disposed in the semi-closed sunshade. The device realizes the rapid and controllable simulation of five kinds of rainfall weather phenomena such as drizzle, rain, snow, sleet and hail in a closed space and provides a detection environment. Actual measurement results show that in a simulated environment, a Doppler-type rainfall radar can continuously and stably identify the five kinds of weather phenomena such as drizzle, rain, snow, sleet and hail and can detect the particle size and speed of the hail. The device can provide the controllable and reproducible detection environment for evaluating the identification accuracy of a rainfall weather phenomenon instrument.

Description

technical field [0001] The invention relates to the field of meteorological observation, in particular to a comprehensive meteorological observation environment simulation device. Background technique [0002] According to the "Precipitation Phenomenon Instrument Functional Specification Requirements Book (Trial Version)" (November 2013) issued by the Observation Department of the China Meteorological Administration, the precipitation phenomenology instrument needs to realize five kinds of weather such as rain, drizzle, snow, sleet, and hail. Automatic observation and identification of phenomena. Among them, the recognition accuracy of precipitation weather phenomena is not less than 90%, the frequency of data output is 1min interval, and the range of precipitation intensity during normal operation is 0-6mm / min. [0003] In the 1930s, the United States first developed and used an artificial rainfall simulation system, and the simulated rain intensity and raindrops were rela...
