humidity
 

can anybody explain the difference b/w absolute humidity and specific humidity in the most simplest way as to me both seems same thing.

one more thing what is the horizontal distribution of relative humidity and how to explain it?

[B][/B][B][/B Q:name four types of condensation, two at ground level and two above ground level ? ans:) ground level (a) dew (b) white frost. above ground (a) fog (b) clouds. am i right ??

specific humidity is defined as
specific humidity = mass of water vapor/total mass of air.
or It is the weight of water vapor (moisture) present in a unit weight of air. It is generally expressed as mg/kg.

The Absolute Humidity of a parcel of air is expressed as:
Absolute Humidity = mass of water vapor/ volume of air.
or It is the amount of water vapor present in a unit volume of air

Relative Humidity is defined as
RH = vapor pressure/saturation vapor pressure = e/es
It is the percentage ratio of the amount of moisture in a given volume or space.

basic causes of rainfall and precipitation producing processes means same thing ?

rain is liquid form of precipitation, while non liquid forms of precipitation are snow, hail etc. Gravity causes fall of droplet.
