The Stevenson Screen is a unit which is used to house thermometers and other weather instruments. In this video, Benjamin explains the Stevenson Screen and its use.
MIND BLOWING EXPLANATION.... THAT'S CLEARLY UNDERSTANDABLE 👏.... BTW SIR....WHY THE HYGROGRAPH ISN'T WORKING....AS IT DEFINED AS 'CONTINOUS RECORDING IN MOISTURE"
Because Minimum type has a metal part inside that will sink into the bulb if left vertical (5 degrees angle needed) and the Maximum one is like a fever thermometer and if left upright will lose the MAX reading over time. Wet and dry bulb are normal type thermometer and are meant to stay vertical.
There are a number of videos available on that, even a few websites. Not mentioned in the video: The screen must be placed at least twice as far away from the nearest tallest object. That includes trees that can pump out large amounts of water vapor while buildings tend to retain heat and radiate it when the air gets cooler.
