What is the main factor that causes rainfall?
What is the main factor that causes rainfall?
What causes rain? Clouds are made of water droplets. Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain.
What does rainfall distribution mean?
n. 1 precipitation in the form of raindrops. 2 (Meteorol) the amount of precipitation in a specified place and time. population distribution n. How the population is spread over an area.
How does temperature affect rainfall?
As average temperatures at the Earth’s surface rise, more evaporation occurs, which, in turn, increases overall precipitation. In addition, higher temperatures lead to more evaporation, so increased precipitation will not necessarily increase the amount of water available for drinking, irrigation, and industry.
Which is the most significant factors affecting on Maharashtra rainfall distribution?
Maharashtra: The most important factor which influences the climate is the towering presence of the Western Ghats which block the monsoon-bearing winds coming from the Arabian Sea and cause rainfall in the Western part and the Marathwada and Vidarbha region experiences low rainfall as it becomes a rainshadow region.
How does altitude affect rainfall?
RA increased with altitude, although Mt. Some previous studies reported that the proportion of hours with rain tended to increase with altitude ( Kuraji et al. 2001), whereas Yoshino (1986) suggested a higher intensity of rainfall in mountains than in the lowlands.
What causes less rainfall?
The proximate or immediate cause of a rainfall shortage may be due to one or more factors including an absence of available moisture in the atmosphere; large scale subsidence (downward movement of air within the atmosphere) which suppresses convective activity; and the absence or non-arrival of rain-bearing systems.
How can we increase rainfall?
How to (Try to) Make It Rain
- Seeding the Sky. The most widely used weather-modification technique is probably cloud seeding, which involves priming clouds with particles of silver iodide.
- Rain Rockets. Airplanes aren’t the only way to seed clouds.
- The Atmosphere Zapper.
- Ice-Breaking Booms.
- Riding the Lightning.
What causes rainfall in India?
The monsoon, which is essentially the seasonal reversal in wind direction, causes most of the rainfall received in India and some other parts of the world. The northeast and southeast trade winds converge in this low pressure zone, which is also known as the Intertropical Convergence Zone or ITCZ.
Which is the main cause of India rainfall?
34.18 Rainfall during June – September constitutes the rains due to monsoon, which is the major source of rain in India.
