What is the relative humidity when the air temperature is at dew point?
When the air temperature reaches the dew point, water droplets that are in the air become visible. This is how you would get fog. Relative Humidity goes soaring to near 100%.
Which has more fog cold water and warm water?
Warm water has more fog due to great humidity
What type of weather is associated with fog?
The weather will be cold outside with little wind and high humidity. Be careful in this type of weather because you won't be able to see very well outside.
Why does relative humidity increase at night?
because land heats up and cools down very fast so at night when the sun is not there the land starts to cool down quickly and the excess of heat is sent back by long wave radiation
Does heat and humidity cause the atmosphere to become dense?
Warm air is less dense than cold air, which is the operating principle behind hot air balloons. I'm not sure of the effect of humidity on air density. That is a good question. Some humid air seems to float pretty well, as in high altitude clouds, while other humid air hugs the ground, such as fog.
Why does the windshield of a car fog up?
The presence of high humidity, and a difference in temperature between the inside and outside.
Why fog form when humidity is high and temperature is low?
When humid air near the ground cools below it's dew point, Fog is formed.
When the humidity is high and the temperature is low fog often forms why?
When humid air near the ground cools below it's dew point, Fog is formed.
When the humidity is high and the temperature is low fog oftens forms. why?
When humid air near the ground cools below it's dew point, Fog is formed.
What must be present in order for a fog to happen?
high humidity
How is fog tracked?
Fog is usually tracked by taking readings of temperature and humidity. Fog can sometimes be spotty but usually can be predicted with great accuracy.
When the humidity is high and the temperature is lowfog often formsWhy?
When humidity is high there is lot of moisture which means a high dew point. When the temeprature drops to the dew point at night or early morning then the air can no longer hold the moisture and it condenses and forms fog.
What is the name of a mixture of air and fog in high humidity?
You may be referring to steam.
What are some synonyms of water vapor?
Water vapor is fog and high humidity.
What is the relationship between humidity and condensation?
High humidity will cause condensation on a relatively cold surface, because the thin layer of air surrounding the surface cools below the dew point and can no longer hold the water vapor. Clouds and fog occur because the air temperature has fallen below the dew point .
Is humidity a percentage?
Yes, humidity is expressed as a percentage. When the dewpoint and the humidity are nearly the exactly the same or exactly the same as the air temperature, you'll have fog. The higher the dewpoint, the more humid it will feel.
What is the relative humidity when the air temperature is at dew point?
When the air temperature reaches the dew point, water droplets that are in the air become visible. This is how you would get fog. Relative Humidity goes soaring to near 100%.
