Hail monitor and its monitoring method

Abstract

The invention relates to a hail condition monitor and a monitoring method thereof. The hail condition monitor comprises a shell and is characterized in that a hail grain size and density monitoring unit, a total natural precipitation monitoring unit, a liquid rainfall monitoring unit, a controller and a storage battery are arranged in the shell; the hail grain size and density monitoring unit is composed of a cube-shaped grain size observation bucket, an X-direction high-speed camera, a Y-direction high-speed camera, an image buffer cover I and an image buffer cover II; the lens central lines of the X-direction high-speed camera and the Y-direction high-speed camera intersect, and the intersection point coincides with the central line of the grain size observation bucket; the total natural precipitation monitoring unit is composed of a total amount collecting bucket, a funnel-shaped guide plate and a horizontal base with a weighing sensor; the liquid rainfall monitoring unit is composed of a liquid collecting bucket, an ice-water separation grid plate, a guide barrel and a horizontal base with a weighing sensor. The functions of monitoring the grain size, duration, density and amount of hail are integrated, all-weather real-time online monitoring is achieved, and the monitoring data accuracy is high.

Description

technical field [0001] The invention relates to hydrological monitoring and meteorological monitoring technology, in particular to a hail condition monitor and a monitoring method thereof, which are suitable for monitoring the particle size, duration, density and amount of hail, and can also be used for monitoring natural precipitation. technical background [0002] Hail is a natural phenomenon and a kind of natural disaster, but for a long time, there is no equipment that can effectively monitor hail at home and abroad. At present, most of the methods used to monitor the hail situation are manual observations, and the artificial observations have large errors in the size, duration, density, and amount of hailstones. The formation of hail is often accompanied by rainfall, and ice has the characteristics of melting when it meets water, so it is difficult to observe effective data in time. Hail slabs are a traditional tool for hail detection, that is to use the imprints of ha...

AI Technical Summary

Problems solved by technology

At present, the methods used to monitor the hail situation are mostly manual observations, and the hail particle size, duration, density, and hail volume obtained by manual observations have large errors

The formation of hail is often accompanied by rainfall, and the ice has the characteristics of melting when it meets water, so it is difficult to observe effective data in time

Hail slabs are a traditional tool for hail detection, that is to use the imprints of hailstones on the hail slabs to obtain the particle size and density of the hail, but the imprints of the hailstones on the hail slabs are usually overlapping, and it is difficult to distinguish manually The number of times of impact and the particle size of the hailstone are repeated, so the measurement of the particle size and density of the hailstone is quite inaccurate

Rain gauges are usually used to monitor rainfall, and can also monitor the amount of hail, but cannot complete the monitoring of hail density and particle size
