The movement of hot and cold air masses relative to each other is primarily responsible for the different rainfall patterns that occur around the world. … It cools off at the higher elevation, and this condenses water out of the air and creates rainfall. If the temperature is cold enough, the precipitation falls as snow.
Why is rain different in different places?
Precipitation rates vary globally and over time. Rain doesn’t fall in the same quantity in any place around the world. Polar areas are dry because cold air cannot hold as much moisture as warm air so precipitation can’t occur so often. …
Why is the weather different in different places?
There are differences in climate around the world because of differing amounts of radiation received from the Sun at different parts of the Earth at different times of the year. More heat from the Sun is received near the equator than near the north and south poles where the angle of the Sun’s rays is lower.
What are the 4 types of rain?
The different types of precipitation are:
- Rain. Most commonly observed, drops larger than drizzle (0.02 inch / 0.5 mm or more) are considered rain. …
- Drizzle. Fairly uniform precipitation composed exclusively of fine drops very close together. …
- Ice Pellets (Sleet) …
- Hail. …
- Small Hail (Snow Pellets) …
- Snow. …
- Snow Grains. …
- Ice Crystals.
What causes change in rainfall patterns?
As temperatures rise and the air becomes warmer, more moisture evaporates from land and water into the atmosphere. More moisture in the air generally means we can expect more rain and snow (called precipitation) and more heavy downpours.
Which country rains most?

|2||São Tomé and Principe||3,200.00|
|3||Papua New Guinea||3,142.00|
Why does it rain on one side and not the other?
On one side of the mountain, wet weather systems drop rain and snow. On the other side of the mountain—the rain shadow side—all that precipitation is blocked. … This cool air cannot hold moisture as well as warm air. Cool air forms clouds, which drop rain and snow, as it rises up a mountain.
Why do regions have different climates during the same seasons?
The different kinds of weather you might experience in these regions are caused by moving patterns in the Earth’s atmospheric and oceanic circulation, unequal heating of the Earth, and the rotation of the Earth on its tilted axis.
Are weather patterns the same in all parts of the world?
Even though there’s only one atmosphere on Earth, the weather isn’t the same all around the world. Weather is different in different parts of the world and changes over minutes, hours, days, and weeks. Most weather happens in the part of Earth’s atmosphere that is closest to the ground—called the troposphere.
What does Itcz stand for?
The Intertropical Convergence Zone, or ITCZ, is the region that circles the Earth, near the equator, where the trade winds of the Northern and Southern Hemispheres come together.
What is the smell of rain called?
Humans aren’t the only ones to appreciate the earthy aroma after an April rain shower. That smell—known as petrichor—stems from microscopic streptomycete bacteria in the soil that produce a compound called geosmin, The Times reports.
Can a cloud burst?
cloudburst, a sudden, very heavy rainfall, usually local in nature and of brief duration. Most so-called cloudbursts occur in connection with thunderstorms. In these storms there are violent uprushes of air, which at times prevent the condensing raindrops from falling to the ground.
What is heavy rain called?
Definitions of downpour. a heavy rain. synonyms: cloudburst, deluge, pelter, soaker, torrent, waterspout.
How are rainfall pattern decided?
Explanation: The prevailing wind patterns decide the rainfall patterns. South west and north east monsoons bring rain in large parts of India. Air patterns, which in turn are decided by oceanic winds that blow throughout the world.
Why was the pattern of snowfall and rainfall changed?
Glaciers have always been the only source of water. Agriculture is completely dependent on glacier melt unlike the rest of river/monsoon-fed India. But over the years with increasing effects of climate change, rainfall and snowfall patterns have been changing, resulting in severe shortage and drought situations.
Why has the pattern of snowfall and rainfall changed?
The pattern of snowfall and rainfall has changed with increasing effects of climate change. Glaciers are significant for irrigation because they provide water in the months of April/May which is crucial for irrigation. … The ice formation continues for 3 to 4 months.
