Types of wind

Types of wind - Wind is moving air caused by the rotation of the earth and also because of differences in air pressure around it . Wind moves from high pressure to low air pressure .
When heated , the air expands . The air becomes lighter swelled so ride . When this happens , the air pressure drops because they reduced the air . Cold air flows around it to the low pressure earlier . The air becomes heavier and shrink down to the ground . On the ground the air gets hot again and ride back . The flow of hot air rising and falling of the cold air convection dinamanakan .
The sea breeze (English : sea breeze ) is a wind that blows from the sea towards the land which generally occur during the day from 09.00 until 16.00 in the coastal areas . The wind is usually obat alami sariawan exploited by fishermen to return from fishing at sea . The sea breezes occur during the day . Because water has a greater heat capacity than land , sea sun heats more slowly than land . When the land surface temperature increases during the day , the air above the terrestrial surface increase as well due to conduction . The air pressure on land will be lower because of the heat , while the air pressure at sea tends to be higher because of the cooler . The result is a pressure gradient from the higher sea to land lower , thus causing the sea breeze , where the strength is proportional to the temperature difference between land and sea . However , if there are offshore winds faster than 8 km / h , then the sea breeze does not happen
Onshore wind (English : land breeze ) is a wind blowing from the inland to the sea which usually occurs during the night from 20:00 hours to 06:00 hours in the coastal areas . This type of wind for the fishermen to go catch fish with a simple wind -powered boat . At night the land to cool faster than the ocean , because the land is lower heat capacity than water . As a result, the temperature differences that cause the sea breeze slowly disappear and instead appear opposite the pressure difference due to the air pressure over the oceans hotter it becomes lower than the mainland , so there onshore wind , especially when the sea breeze is not strong enough to fight it
Foehn wind / wind fall is the wind that occurs after orographic rain . the wind is blowing in a region with different temperature and humidity . Foehn wind occurs because there is no movement of air masses that rise high mountains over 200 meters on one side and down the other side . Foehn winds that fell from the top of the mountain is hot and dry , because water vapor has been discharged at the time of orographic rain .

Usually this is a hot wind damage and can cause casualties . Plants were exposed to the wind can die and humans affected by these winds could down her immune system against disease
Munsoon wind , Moonsun , monsoon is a periodic wind blowing ( at least 3 months ) and the period of each other opposite pattern will change in the opposite direction every half a year . Usually in the first half of the year the wind blows dry land and a half years following the sea breeze blowing wet .

In the months of October to April , the sun is in the Southern Hemisphere , thus the Australian continent gained more solar heating of the Asian continent . As a result, in Australia there is a center of low air pressure ( depression ) , while in Asia there are centers of high pressure ( compression ) . This condition causes the airflow from the Asian continent to continent of Australia .

In Indonesia, this wind is Northeast monsoons in the Northern Hemisphere and West monsoon in the Southern Hemisphere . Because the wind is passing through the Pacific Ocean and the Indian Ocean bring much moisture , so the rainy season in Indonesia occurred . The rainy season covers the entire territory of Indonesia , it's just not evenly spreading . further eastward diminishing rainfall as the water vapor content of less and less .

In the months of April to October , the sun is in the northern hemisphere sky , so the Asian continent hotter than the continent of Australia . As a result , in Asia there are centers of low pressure , while in Australia there are centers of high pressure air that causes winds from australia towards asia .

In Indonesia occurred east monsoon in the southern hemisphere and the southwest monsoon in the northern hemisphere . Therefore, do not cross the vast ocean breeze does not contain a lot of water vapor in Indonesia therefore occurred dry season , except for the west coast of Sumatra , Southeast Sulawesi , Irian Jaya and the south coast .

Between these two seasons are no seasons called transition season ( transition ) , which kemareng season which is the transition from the rainy season to the dry season , and anchoring season which is transition rainy season to the dry season . The characteristics of the transition season are: The air was hot , the wind direction and irregular rainfall occurs suddenly in a short time and bushy .

Munson wind is divided into two , namely the West Munson , known as Season Winds West and East Munson , known as the East Wind Season
