about weather why cyclone are low pressure and anticyclone are high pressure?

Answer 1

Because the wind goes clockwise around a cyclone and anticlockwise round an anticyclone.

Answer 2

Anticyclones (High Pressure)
Areas of sinking air which result in high pressure are called anticyclones. The opposite to an anticyclone is the cyclone or depression.
High pressure systems have low pressure gradients (ie the air pressure doesn't change rapidly). This means that the winds are gentle. As the air sinks, it warms up, leading to warm and dry weather.
Anticyclones are much larger than depressions and can lead to many days or weeks of settled and calm weather. Anticyclones often block the path of depressions, either slowing down the bad weather, or forcing it round the outside of the high pressure system. They are then called 'Blocking Highs'.
As air descends, air pressure increases. When air hits the ground, it has to go somewhere. The earth's rotation makes the air change direction. In the Northern Hemisphere the air is pushed clockwise. In the Southern Hemisphere the air is pushed anticlockwise. This can be seen in the diagram below.


Characteristics of Summer Anticyclones
Hot days with few or no clouds. Light winds. Cooling of ground leading to morning mist. Warm moist air rising from the ground forming thunderstorms. Cloud cover over Eastern England caused by light winds blowing over the cooler North Sea.

Characteristics of Winter Anticyclones
Cloudless skies but less radiation due to the low angle of the sun. Temperature drop, making the days cold and the nights even colder due to lack of cloud cover. Fog and frost forming at night. Cold air from Asia bringing snow to the East.

Cyclones (Low Pressure)

Low pressure systems or depressions bring the cloud, rain and wind that we usually associate with British weather. Low pressure systems develop when less air flows into an area than out of it. They are the opposite in nature to high pressure systems or anticyclones.
When the two different air masses meet, a front is formed.
When the warm air approaches the cold air, the warm air is forced to rise over the cold air. This forms a warm front.
When the cold air approaches the warm air, the warm air is also forced to rise over the cold air. This forms a cold front.

Answer 3

What old know all says is true in the southern hemisphere. The opposite is true in the northern hemisphere

The word cyclone means moving in a circle (it is related to the word cycle) and comes from Greek. The low pressure areas have much more pronounced circular motion, so it is unsurprising that this feature was picked on for the name.

Answer 4

Low stress is seen a valley, collectively as severe stress is stated as a hill. Low stress is the place typhoon are, they are many times linked with a chilly front, marked via a blue spike line, this brings wet and if the low is powerful adequate, it particularly is indicated via a falling barometer, winds ought to be unfavourable. severe stress is many times linked with very astounding climate, notwithstanding there are some events the place the climate would nicely be somewhat moist, then we call that a grimy severe. The anti cyclones are the way the typhoon rotate, interior the Northern hemisphere, they many times are counter clockwise. notwithstanding, now not all low stress provide rain, here interior the West Coast, we can get somewhat warm with what we call a warmth low, or thermal low.

Answer 5

Why are they complete opposite?,is that the question?Well,Low pressure or Cyclones spin in and anti clock wise direction,which is dictated by the earth spinning on its axis(Coriolis),what really makes them different is the fact that,low pressure area are areas that attract moister and air because of heat generated by the sun,so these areas are favorable as they are areas for high concentration,for development.(which can prolong for more than several days).

High pressure, are areas that experience rapid cooling, as air sinks and is, is taken away to a low pressure area.(high pressure spins in a clock wise direction)
High pressure areas also earn the name in the fact that they are phenomenons that do not cause alot of rain to occur,but instead give fair Sunny days and windy conditions that may persist for several days,or longer.
NB;In the southern hemisphere both spectacles of nature are in complete reverse in direction when compared to the northern hemisphere.
