Different types of Humidity
|
Humidity can be measured with the help of a device called hygrometer or psychrometer. Globally, on a larger scale it is measured using satellites which find the amount of water present in the troposphere at the heights of 4 to 12 kms. Those satellites that measure the content of water vapor have certain sensors which use infra red rays. This is very crucial for observing climatic conditions such as thunderstorms, and also to forecast the weather. Humidity can be regulated with a humidistat along with a de-humidifier. It functions somewhat like a thermometer or thermostat.
Humidity and rain
A minimum of 100% relative humidity is required for the formation of clouds so that rain can fall. This needs to happen only in places where the formation of clouds is taking place. Normally the rain which falls does not have saturated humidity . Some portion of the rain can escape as vapor, thereby raising the humidity .
Problems of humidity
- Excessive humidity can result in heatstrokes and general body fatigue.
- Electronic gadgets may not function well in places having high humidity levels.
