Because plants give off water vapour, thus increasing the humidity nearby.
The average relative humidity on a rainy day would be closer to 100 percent humidity. Rain adds moisture to the air, increasing the humidity levels to near saturation point. This leads to a higher average relative humidity compared to a non-rainy day.
If the amount of moisture did not change, the relative humidity would be lower because there would be less moisture in the air relative to how much that hot air could hold.
The relative humidity would be quite low.
You would use both to determine the relative humidity.
Relative Humidity is measured with a HygrometerHumidity is the amount of water vapor in the air.On hot days, when it feels sticky, the humidity would then be high.
If the water vapor amount stayed the same, then the relative humidity would be greater.
Relative humidity is the ratio of specific humidity to the overall capacity. So in this case it is 10/50, or 20 percent.
Relative humidity at 15°C depends on the amount of moisture in the air. Relative humidity is a measure of how much water vapor is present compared to the maximum amount the air can hold at that temperature. For example, if the air contains half the moisture it can hold at 15°C, the relative humidity would be 50%. To determine the exact relative humidity, you would need to know the specific moisture content of the air.
That would be "dewpoint"...When the air temperature falls to the dewpoint (or dewpoint rises to the air temperature), then you have 100% relative humidity.
It is not possible to know the relative humidity of a place with 32 degree celsius. It varies with location. For example, in tropical areas like Singapore, 32 degree celsius could still mean a relative humidity of 90% but in desert areas, 32 degree celsius would still have a low relative humidity. So temperature and humidity are not totally related.
Relative humidity can vary during rain, depending on factors such as temperature and amount of precipitation. Generally, during rain, relative humidity tends to be close to 100% due to the presence of moisture in the air from the rain.
Relative humidity becomes the ratio between the actual amount of water vapor present to the capacity that the air has at a particular moment. Just to be an optimist, if the glass is half-filled, the relative humidity is 50 percent. If the glass is three-quarters filled, the relative humidity is 75 percent.
