Weighing rain gauge structure suitable for measuring freezing rain precipitation

Abstract

The invention provides a weighting rain gauge structure suitable for measuring freezing rain precipitation. The weighting rain gauge structure comprises a housing and an inner barrel, an inner barrel bracket, a freezing rain collection disc, a precipitation collection barrel, a precipitation collection barrel weighting sensor and a total weighting sensor which are arranged in the housing, wherein the housing and the inner barrel are movably connected at the top ends to form a water receiving opening; the precipitation collection barrel is arranged on the precipitation collection barrel weighting sensor; the outlet of the inner barrel is positioned right above the precipitation collection barrel; the precipitation collection barrel weighting sensor is arranged on the total weighting sensor; the inner barrel is also arranged on the total weighting sensor through the inner barrel bracket; the freezing rain collection disc is disc-shaped, arranged in the inner barrel and positioned under the water receiving opening and the diameter of the freezing rain collection disc is greater than that of the water receiving opening. The weighting rain gauge structure provided by the invention can obviously improve freezing rain precipitation measurement accuracy and provide reliable scientific data for scientific research on the disaster of freezing rain.

Description

technical field [0001] The invention relates to a rain gauge, in particular to a weighing rain gauge structure suitable for freezing rain precipitation measurement. Background technique [0002] Precipitation measurement is an important part of surface meteorological observation and an important part of atmospheric water cycle monitoring. Precipitation measurement is aimed at the liquid or solid (after melting) water that falls from the sky to the ground, and measures the accumulation depth of precipitation on the horizontal surface that has not evaporated, infiltrated, or lost within a certain period of time, that is, the amount of precipitation. Instruments used for precipitation measurement include the following main categories: rain gauges, tipping bucket rain gauges, siphon rain gauges, and weighing rain gauges. [0003] The rain gauge is composed of a rain gauge and a measuring cup, and the rain gauge includes a water receiver, a water storage bottle and a water stora...
