Description

Novel wind-shield ring design of rain gauge

The outer cylinder of the commonly used rain gauge is a cylinder with the height of 523mm and the outer diameter of 220mm, and is arranged on the ground surface. When the rainfall is measured, the falling track of the raindrops can be changed by horizontal wind, and the rain measuring cylinder arranged on the ground changes the surrounding wind field to a certain extent, so that the raindrop collection rate has larger error. Experiments show that the rain drop collection rate of a common rain gauge is reduced by 2% -10% due to the deformation error of a wind field, and the accuracy of the obtained measurement value is greatly reduced particularly in a strong wind environment.
