to protect the instruments inside from the wind!
A Stevenson screen is a ventilation box used to house meteorological instruments, primarily thermometers and hygrometers. It is typically made of wood or synthetic materials and features slatted sides to allow for free air circulation while protecting instruments from direct sunlight and precipitation. The screen is painted white to reflect sunlight and minimize heat absorption. Its design ensures accurate temperature and humidity readings by maintaining a stable environment for the instruments inside.

The sides of a Stevenson screen are louvered to allow air to circulate freely around the temperature and humidity sensors inside. This design helps prevent the sun's direct rays from hitting the sensors and affecting the accuracy of the readings. The louvered sides also help to reduce the impact of thermal radiation on the inside of the screen.

In observataries,the thermometers are kept in a wooden box with good ventilation and air movement.This box is called stevenson's screen
A Stevenson screen is a white slatted wooden box with a double roof design, used to shield temperature and humidity sensors from direct sunlight and precipitation. Its key characteristics include proper ventilation to ensure accurate measurements, a standard size of about 30 cm in height, and a location placed 1.25 to 2 meters above the ground.

The louvered sides allow outside air to flow around the thermometers. ... Stevenson screens are always installed so that the door opens facing north, to keep the sun from shining directly on the thermometers and affecting the readings.
