Observations show that changes are occurring in the amount, intensity, frequency and type of precipitation. These aspects of precipitation generally exhibit large natural variability, and El Niño and changes in atmospheric circulation patterns such as the North Atlantic Oscillation have a substantial influence.
Pronounced long-term trends from 1900 to 2005 have been observed in precipitation amount in some places: significantly wetter in eastern North and South America, northern Europe and northern and central Asia, but drier in the Sahel, southern Africa, the Mediterranean and southern Asia. More precipitation now falls as rain rather than snow in northern regions. Widespread increases in heavy precipitation events have been observed, even in places where total amounts have decreased.
These changes are associated with increased water vapour in the atmosphere arising from the warming of the world’s oceans, especially at lower latitudes. There are also increases in some regions in the occurrences of both droughts and floods.
Dear Shaileyee;
I think this video could help you:

The rain plays a crucial role in shaping the landscape and bringing nutrients to the creatures for survival, whether it is an ocean ecosystem or mountain eco systems such as in Indian Himalayan region. The geographical concepts of mountains acting as rain shadow and rain shedding natural structures are interlinked. In this way, rain not only enrich in variety of flora, fauna, human communities and cultural diversity but also important as a provider of life, offering water to a huge part of the Indian Himalayan subcontinent. But in recent past, continuing climate change and anthropogenic activities brings significant changes in the climate and precipitation pattern of the Himalayan area. As a result the, state in Indian Himalayan Zone, is currentl Cloud burst, downpour, overwhelming precipitation and ensuing avalanches. agriculture lands, infrastructure, and further insecurity of m accidents in Uttarakhand Himalaya area arising every year and hence, lots of discussions are going on how climate change is seeking revenge on mankind by endowing us with disasters! These cloudbursts i occurrence of extreme event due to climate change. In this foundation, the main aim of this paper is to investigate and find the factors responsible for increased intensity of cloud burst and the extreme rainfall e Uttarakhand through recent rainfall data. The paper likewise takes a gander at and examines different choices for disaster risk diminishments and reductions in the sensitive eco zone like Uttarakhand. Read the mentioned article.
