The Optical Weather Phenomenon Developed by Anko Observed the Blizzard Process

[China Instrument Network Instrument R&D] From January 3rd to January 5th and January 24th, Anhui has witnessed continuous rain and snow, which has a wide range, long duration, and severe impact since the beginning of the winter. The optical weather phenomenometer independently researched and developed by the Institute of Environmental Optics at the Anhui Institute of Optics and Optics Co., Ltd. recorded the complete blizzard process in real time. The monitoring data included the onset time of the snowfall phenomenon, the instantaneous snowfall intensity, the particle size distribution of snowfall particles, and the visibility during snowfall. Radar reflectance and many other important meteorological parameters.

The weather phenomenometer located in the northwestern suburb of Science and Technology in Hefei City monitored that there was a continuous 35-hour continuous snowfall process from 9:00 am on January 3 to 8:00 pm on January 4, during which the snowfall intensity continued. Stronger, the maximum snowfall intensity occurred at about 7:00 pm in the month of January, when the instantaneous snowfall intensity reached 10 mm/hour, and the particle size of the snowfall particles reached 6-7 mm, and the corresponding visibility was reduced to below 400 meters. The duration of the snowfall process from January 24th to the present has also reached more than 30 hours. During this period, the snowfall intensity is also strong. The maximum snowfall intensity reaches 7mm/h at 11:29am on the 25th, and the average snowfall particle size distribution is 4mm. Within this time, the visibility was reduced to about 500 meters.

Optical weather phenomena instrument is mainly used for on-line monitoring of precipitation, sight and other weather phenomena, using particle extinction signal to detect droplet size information such as particle size and velocity, and inversion of parameters such as weather phenomena and precipitation information. The technical indicators of this instrument have reached the advanced level of similar products of the world, and have obtained a number of authorized invention patents and software copyrights; it has obtained the "Utilization Permit for Meteorological Special Technical Equipment" issued by the China Meteorological Administration, and has been used in many places across the country for demonstration applications. The enterprises have cooperated to carry out equipment industrialization and engineering research and development; formed product sales in areas such as meteorology and traffic safety, which changed the situation in which relevant commercial meteorological monitoring equipment in China depends on imports. The R&D of this instrument was supported by the STS regional key project of the Chinese Academy of Sciences and the enterprise cooperation project of the Hanjiang Emerging Industry Technology Development Center.
