Rising Air Delivers Precipitation!

Precipitation of moisture in the air is the primary way that new safe water is delivered everywhere. Nearly all of this precipitation happens naturally as part of what we call the Water Cycle. If we could raise air artificially or manually, we could deliver safe water anywhere!
Air Circulation

Rising and descending air

Large-scale rising and dropping air is a characteristic of the atmosphere. 
The location of both rising and descending air vary by location (by latitude and longitude) and by season (as the axis of the earth changes relatively to the sun as the Earth rotates around the sun.
The wettest areas are seen in the areas where air is 'naturally' rising i.e. at the equator and the mid-latitudes  40-60 degrees North and South.
The driest areas are seen where air is naturally descending: 20-30 degree North and South latitudes and around the poles.
Drivers of Rising and Falling air

Causes of Rising and Falling air

The primary causes of air circulation are surface heating, terrain changes, convergence of air masses. There is more rainfall on higher elevations of mountains and as weather patterns create turbulence in the atmosphere.
The rising and falling air moves northwards or southwards by season i.e. how the earth is oriented relative to the sun.
Like mountains, the presence of large bodies of water also influences incidence and rates of precipitation.
Adiabatic Cooling

As air mass rise, pressure on the air mass drops and the air mass cools.

As rising continues, so does the cooling, till water vapor molecules condense and coalesce to form water droplets.

Intensity of precipitation increases as the depth of the rising air mass increases.

Is there any way for us to artificially raise large bodies of air that we know are full of water vapor?

Water Defines Climate Everwhere

Water in the troposphere, the atmosphere closest to the surface, conditions the Earth. In some locations water runs the local heating system while, at the same time, it acts as the cooling system in other locations. Water has an inordinately strong effect on climate. 


What is climate?

Climate Map

Climate is weather averaged over a long period of time, usually, 30 years.
In this averaging, weather is defined by many variables. The predominant variables are temperature, precipitation and wind movement.


Temperature

Air Temperature Variations

Temperature is a measure of the 'heat' in any location.
This 'heat' is the sum of the amount of energy deposited on a place by sunlight and the amount of energy existing on Earth at that place.
Water in the atmosphere and in surface bodies acts as the controller of heat distribution around the planet.
Water in the wind moves heat from one location to another.
Ice sheets and clouds cool the Earth's surface by reflecting the heat energy back into space.
Ocean and river currents transport heat to locations far and near.

Precipitation IS water - in every form that water exists!









Water's Venetian Blind effect

Source - b4i.ie

Water in the air (with other greenhouse gasses like carbon dioxide) acts in much the same way as slats in a Venetian blind. 
The angle of each slat influences how much of the suns' heat and light enters a room. We can move the slats to form a 'closed' surface to, in effect, stop most light and heat from entering a room. We can fully 'open' the blinds to allow entry of the most amount of light and heat into a room.
In a similar way, nature manipulates the water content of air at individual locations (in conjunction with other parameters) to influence (raise and lower) in a very large way the temperature at a particular location.
