If the speed is less near the ground than it is at higher altitude, then the top of the
wavefront moves ahead of the bottom, and the wavefront appears to "keel over",
causing a downward bend of its velocity vector.
Radio waves exhibit the same identical phenomenon in the presence of the typical gradient
of atmospheric refractivity with altitude.

When are you most likely to encounter fog?
Fog occurs when 1) humidity goes up and 2) temperatures go down.
Do seismic waves speed up or slow down as they travel downward and reach the Moho?
Speed up
How are temperature and humidity not related?
By marriage. Humidity and temperature are related. The maximum absolute humidity increases with temperature and pressure (up to the boiling point).
As air is heated its relative humidity?
Air expands when it is heated.
How can relative humidity and dew point be used to predict the weather?
Relative humidity expresses a percentage of humidity in the air to the maximum amount of humidity that could be in the air. For example: when the temperature rises the air will be able to hold much more humidity so the relative humidity will drop.
How does low humidity affect travel?
it affect travel because of sand storms because it can clog up the plans engines
What does humidity do for you body?
"its not the heat , its the humidity" usually means it is the the humidity that cools your body temperature down .
How fast does humidity travel through the air?
Humidity is a condition of a gas, you add moisture to a gas to increase it's humidity and dry it to reduce the humidity when air gets to 100% humidity it may rain?
How a device to measure relative humidity was made in BC times?
A device to measure relative humidity in BC times was done with a simple twig placed parallel to the ground and mounted several feet up. When relative humidity increases, the twig points down, and when it decreases, the twig points up.
Which way do planes travel?
Up & down, there & back. Aircraft travel in all directions.
What is relationship between relative humidity and temperature?
There is an effect if you're a living being and trying to cool down. Humidity does not change the temperature. It will make it difficult for your body to cool down, so it 'feels' hotter with humidity. Sweat has to evaporate for your body to cool down. It's harder to evaporate when the air is already saturated with water (ie high humidity).
What important factors does humidity contribute to weather?
When humidity goes down, you want to avoid putting on Fires. The lower the humidity, the larger the chance of a forest fire starting! Until the humidity goes back up, you shouldn't start a fire anywhere. Yes, fire danger is a type of weather as well.
When are you most likely to encounter fog?
Fog occurs when 1) humidity goes up and 2) temperatures go down.
Can you travel with the blinds down in a rv mobile home?
Yes, you can travel with the blinds down in an RV mobile home. If you'd rather have them up, you can do that too.
What does hair have to do with determinig the level of humidity in the air?
When girls hair frizz up it is because of the humidity in the air. If their hair frizzes up a little bit there is not much humidity in the hair. Now if their hair frizzes up really bad there is a lot of humidity in the air.
How do people from Amazon rainforest travel?
They have to travel by foot. They sometimes use boats for getting up and down rivers.
Does humidity cause any effect on drying of porous or non porous solid?
Humidity is a mayor factor in thing drying. Needles to say a porous material is likely to have water within it and therefore will dry more slowly. However regardless of the material high humidity at the time will slow down the drying process and low humidity will speed it up.
