what are the conditions necessary for rain to fall?
605786
Solution: 1) The air must contain water vapor that can precipitate, 2) the moist air must cool down in order to release water in liquid form, and 3) there must be condensation nuclei for water vapor to condensate on.

Data networks and history Bureau weather stations record a variety of aspects of the weather including temperature, humidity, rainfall, air pressure, sunshine, wind speed and direction, cloud and visibility. Stations which measure rainfall are the most common.

1, Convectional Rainfall: it is caused due to high temperature and low-pressure area, winds go up and when gets moisture rainfall occurs. 3. Frontal Rainfall: Either due to tropical cyclone or temperate cyclone,formation of cumulonimbus clouds takes place,and rainfall occurs.

Clouds form when water vapor 'condenses' around small particles in the air. Precipitation occurs when the products of condensation coalesce to form water droplets that are too heavy to be supported by the upward motion of the air. The water droplets fall to Earth's surface as rain, or snow.

['cumulus stage. warm, moist air, rises, condenses and forms a cumulus cloud about 4.7 mi. high.', 'mature stage. the cloud grows to become a cumulonimbus cloud about 7.6 mi. high. ... ', 'final stage. the falling precipitation causes a strong downdraft, and the storm dies out as the supply of water vapor used up.']

Weather can change rapidly from a sunny day to a downpour, sometimes with wind and lightning. If it is raining, bring your umbrella and stroll between the raindrops, the Market will be open! Our produce vendors work rain or shine and so do we.

There are basically four elements of weather that can help describe weather. The four elements include wind, temperature, air pressure and moisture. Discuss with students each of the elements.

Humidity, air temperature and pressure, wind speed and direction, cloud cover and type, and the amount and form of precipitation are all atmospheric characteristics of the momentary conditions we call weather.

Light rain — when the precipitation rate is < 2.5 mm (0.098 in) per hour. Moderate rain — when the precipitation rate is between 2.5 mm (0.098 in) - 7.6 mm (0.30 in) or 10 mm (0.39 in) per hour. Heavy rain — when the precipitation rate is > 7.6 mm (0.30 in) per hour, or between 10 mm (0.39 in) and 50 mm (2.0 in) per ...

Air rises in a low pressure area and falls in a high pressure area. In a low pressure area the rising air cools and this is likely to condense water vapour and form clouds, and consequently rain. The opposite is true in a high pressure area, which is why high pressure tends to give cloudless skies.
