Hurricanes can bring much needed rainfall to drought-stricken regions and clear the air of pollutants.
Clouds often bring rain, and the presence of clouds and rainfall makes tropical rain forests possible.
Tropical cyclone over Arabian Sea would bring about heavy rainfall causing flash flooding. Any rainfall in this region can be serious due to the rapid run-off as the rainwater heads down to sea-level. Typically, dry river beds or "wadis" start flowing which hinders the road network.
The figure varies. Some cyclones have more intense winds, while others bring deluges of rainfall. Cyclone Wanda, which was a major factor in the Brisbane floods of 1974, dumped 580mm of rain over Brisbane in three days. There were heavier falls in some areas, with nearby Mt Glorious recording 1,300mm in five days.
That is part of the definition. The description here could apply to both cyclones and anticyclones. A cyclones is a low-pressure wind systems in which wind spirals in a cyclonic direction: counterclockwise for systems in the northern hemisphere and clockwise in the southern hemisphere. Cyclones generally bring stormy or rainy weather. An anticyclone is the opposite; it is a high-pressure system with winds that spiral clockwise in the northern hemisphere and counterclockwise in the southern hemisphere. Anticyclones generally bring clear weather.
It is because the south west monsoons which bring 80 percent of rainfall every year touches the western coast of India first and by the time it moves into the interiors and east, the moisture and rainfall gets reduced. So, the western region is wetter than eastern region.
summer monsoons.
Rajasthan do not recieve rainfall in monsoon because Aravali Range is situated parallel to monsoon winds and hence winds do not strike with aravali and not bring rainfall.
Asia doesn't get any rainfall during the winter because of the monsoon season which does not bring any rainfall during the winter months.
Northern winds
"Jet stream is a swiftly blowing wind at a height of 3 to 5 kms above the subtropical high pressure belt. Himalayas act as a barrier in their path and as such, the jet streams are divided into westerly and easterly jet steams. the westerly jet is responsible for bringing western disturbances into north-west India and Pakistan which bring winter rainfall. the easterly jet blowing over northern India is responsible for bringing tropical depressions over India and Bangladesh. these depressions play an important role in the distribution of rainfall." source: icse geo textbook
The prevailing winds of the west are what generally bring wet weather to Europe. It first crosses over Western Europe, dropping most of its rain there. By the time it reaches Eastern Europe, there is less rainfall.

Monsoons are seasonal, lasting months, not days. Monsoons bring heavy winds and rainfall. India gets about 80 percent of its annual rainfall from monsoons.
The western side of the mighty Indian Western Ghats rise majestically to over 2500 meters above mean sea level to capture the moisture laden trade winds that blow annually once over the India sub-continent. The location of these mountain ranges is such that the South-West Monsoon that break over the southern most tip of the peninsula during the last week of May, block the winds and they steadily rise against the mountain to condense rapidly and give copious rains on the western side. Consequently the eastern side is typically known as the rain shadow region, except those regions that lie close to the natural passes or gaps in these ranges. reghuram.p@gmail.com
