Air Masses of North America or Europe
World distribution of air signs The distribution of different types of air masses in the world, according to the continents, has been discussed under the following points.
“A North America’s air masses There is a lot of difference in the air masses moving over the North American continent. Following are the air masses moving in this continent
1. Polar continental air masses The origin area of CP air mass in winter is the northern region of North America.
Alaska The temperature is found to be low in the glacial region of Canada and Greenland. Inverness of temperature and lack of actual humidity are other characteristics of this region.
This air mass moves from north to south. Usually, this air remains stable in the beginning but like- As it flows towards the south,
it becomes unstable. In summer these air masses are cooler than the earth’s surface, so their lower layer becomes hot due to contact with the surface and that is why this air mass becomes unstable.
Its effect is on the climate of the central United States of America where icy winds affect the entire region.
Polar ocean air masses This air mass is geographically divided into two parts
a. Tunes Pacific Ocean Air Signs The region of origin of these air masses is the North Pacific Ocean.
In the winter, the Aleutian low weight establishes in this area. This region is surrounded by continental polar air masses,
due to which the polar ocean air masses are very cold and dry in winter. But they take water from the oceans on their way and hit the mountain ranges of the west coast of North America, causing thick clouds and rain.
B. Polar – Andha-ocean air-mass These air masses originate in the cold waters of the Atlantic Ocean in the middle part of Cape Cape and New Foundland.
These air masses are born due to the constant cold conditions here. But in winter, due to the influence of westerly winds,
these air signs become somewhat relaxed, but in summer, these air signs remain more effective. The effect of these air masses is visible on the east coast of North America.
Tropical oceanic air masses This air mass originates in the equatorial warm Andean ocean and the Pacific Ocean.
The main reason for the origin of these air masses is the uniform temperature and oceanic conditions throughout the year in these latitudes.
Tropical ocean signs are divided into the following three parts
A. Tropical Anda-Ocean Air Sign –
The development of this air sign is more in Mexico, so these air masses are hot and humid.
These air masses occur in the United Gulf and the Caribbean Sea. These water bodies have high temperatures throughout the year.
The air enters the continent of North America from the southern coast of America to the north. The fog formed due to the influence of the land part of
the Pashil atmosphere and the origin of Mercury would also have been done by these Crashes. Is. Due to the hot surface in summer, these air masses become very intense and destructive.
The southeastern United States of America is affected by these zodiac signs.
Tropical ocean air masses This air mass originates in the tropical Pacific Ocean region. In the tropical Pacific Ocean, there are high temperatures throughout the year.
Due to the high temperature, the percentage of relative humidity remains high in the air here.
Due to the heat of the water in winter, that air mass becomes colder by reaching near the surface parts. These air masses cause more rainfall on the west coast of the United States of America. In summer these zodiac signs become relaxed.
Tropical continental air masses The development of this air mass occurs in the southwestern part of the United States of America and the terrestrial part of Mexico.
Due to the narrowness of this part, the full development of the air masses is not possible here. Due to the continuous high temperature and dryness in summer,
when this amount flows to the northeast, it affects the central plains of the United States of America, but when going to the more eastern part,
the air mass merges with other air masses. Various air signs meet on the continent of Europe. Therefore, due to such a union, their real qualities change in the air signs.
On the basis of their effect on the continent of Europe, these air masses are divided into the following four parts:
Polar oceanic air mass In the north of the continent of Europe, this air develops in Greenland, Iceland, and in the arctic and sub-arctic regions.
Here the uniformity of temperature is found throughout the year. From here this air sign moves south. When this air mass reaches the marginal area or the upper parts of the mountains, it rains heavily.
Due to the increase of cold, stability increases in the air sign, but in the summer when this air sign moves towards the inner parts, its instability increases.
Polar continental air masses These air masses originate in the glacial regions of Russia and Finland.
The flow direction of these air masses is towards the west, but due to westerly winds they are not able to move much towards the west,
when these air masses reach Central Europe, their physical conditions change. These air masses have the characteristics of low temperature, heat inversion, humidity, extreme stability, etc.
Tropical ocean air masses In winter, this air mass originates in the tropical region of the northern and eastern high mass of other oceans.
These air masses flow towards the north. These air masses are more hot and dry, but due to the stagnant air, there is no rain. In the summer, the tropical ocean air mass becomes more relaxed.
Air masses of the Mediterranean region –
Important air masses flow in the Mediterranean region in winter. In winter, an impressive margin is established over the warm waters of the Mediterranean Sea.
Here, due to the size of the polar oceanic mP, polar continental P, and tropical continent CT air masses, the temperature and magnitude of these air masses change.
In these air masses, there is instability and rain due to dense clouds. Cyclonic storms are their main characteristics.
Due to the anticyclonic conditions in summer, hot-dry permanent air is characteristic of the climate of this region.
Air masses of the continent of Asia The air masses of the continent of Asia are divided into the following three parts:
1. Polar continental air masses –
In East and Central Asia, snow accumulation is found for a long time in winter and the temperature remains below the freezing point for a long time.
Due to this, the polar continental air mass develops in the northern part of the continent of Asia.
These air signs are cold and dry at the point of origin, but these air signs improve as they move forward. In the north of India, in the north of the Himalayas,
in the northern part, and in the northern parts of the Yangtsikyang river, the influence of this air sign remains.
When these air masses flow towards the east and leave the continent of Asia and move towards Japan, they absorb moisture from the Sea of Japan.
For this reason, the western coast of Japan receives rain from dense clouds.
Tropical oceanic air masses The origin of these air masses are the oceanic regions near the eastern islands,
The air masses that arise from the equatorial region of the Indian Ocean. They cause rainfall over the coastal parts of East Africa.
‘3. The polar oceanic air mass develops over the oceans to the east of Antarctica, due to which parts of the southern coast of South Africa are affected by this air.
E. Air masses of Australia The air masses of the continent of Australia are divided into the following two parts:
1. Tropical continental air masses This air mass develops in the warm region of Central Australia. Here the effect of high temperature and dry air remains throughout the year.
2. Polar oceanic air masses – July month, which is the month of summer in the southern hemisphere, in the south of Australia,
due to the absence of land masses, the maximum effect of these air masses is found and the development of the polar continental air mass is not possible in these parts.
The Pacific Ocean on the west coast of South America remains dry because unstable air is found on the west coast,
but the east coast has more rainfall. The. The air masses of the continent of Africa are divided into the following two parts
(1). Tropical continental air signs The region of origin of this air mass is the vast Sahara desert in the north of Africa. From this desert,
these air masses flow north and south, which affects the equatorial region and the areas near the Mediterranean Sea. These are dry air masses in which there are dust storms.
(2). High tropical ocean air masses This air mass originates in the equatorial sea area, that air mass is hot, humid, and unstable.
As these air masses reach the continent of North America, there is terrestrial and convective rainfall.
A. Air masses of South America The air masses of South America have divided into the following parts:
1. Tropical and semi-oceanic air masses This air mass originates in the ocean located east of South America.
This wind is warm and steady and is stable, which affects the areas of the eastern coast of the continent of South America.
2. Polar ocean air masses The polar ocean air masses coming from the South Pole are very cold.
