Winds which are generated over a comparatively small area by local terrain and weather. They differ from those which would be appropriate to the general pressure pattern.
What are the examples of local winds?
Answer : Local winds blow only during a particular period of the day or a year in a small area. It is also called the Loo. The two examples of local winds are Land Breeze and Sea Breeze.
Which wind is called local wind?
Mesoscale winds are winds that blow across areas of the surface ranging from a few miles to a hundred miles in width. Mesoscale winds are better known as local winds or regional winds.
What causes local winds?
Small-scale convection currents cause local winds. Local winds blow over a much smaller area and change direction and speed over a shorter period of time than global winds. On a hot summer day at the beach, the land heats up faster than the water. … After sunset, the land cools down faster than the water.
What are the 2 types of local winds?
The main types of local winds are sea breezes and land breezes, Anabatic and katabatic winds, and Foehn winds. You can discover different ways to measure wind speed on our Experiments and Demonstrations page, or on our Top 10 Ideas for Weather Fieldwork page.
What is local wind class 8?
Ans:- Local winds are periodic winds. This is the result of variation in local temperature, pressure, and humidity.
What are local winds 7?
Local Winds: Local winds are unique to certain well-defined areas. They blow over a small area from a small area from a particular period. They affect only the local weather conditions of that place. They are known by different names in different parts of the world.
What are local winds Class 9?
Local winds are those winds which blow over a certain region or a local place only. These winds may be warm or cold depending upon the area from which they blow.

Which is a difference between global and local winds?
Local winds blow from the poles to the equator, whereas global winds blow west to east. Local winds curve due to the Coriolis effect, whereas global winds blow in a straight path. Local winds blow over long distances, whereas global winds blow over short distances.
Which statement best describes local winds?
Which statement best describes local winds? They move over short distances. What do the arrows indicate? Air moves in a direction that creates land breezes.
What are the effects of local winds?
Local winds have very important effects on the weather and climate of some regions as they help to moderate the climate of nearby areas with sudden increase or decrease in the temperature and humidity, but this moderating effect completely depends on the location of the place.
What are the 4 types of wind?
Types of Wind – Planetary, Trade, Westerlies, Periodic & Local Winds.
What is a cold local wind?
Cold Local Winds:
These are dust-laden winds and as they have a temperature below freezing point, they create Cold Wave conditions. Examples of Cold Local winds include Mistral, Bora, Northers, Blizzard, Purga, Lavender, Pampero, Bise, etc.
What are the 5 types of wind?
The Earth contains five major wind zones: polar easterlies, westerlies, horse latitudes, trade winds, and the doldrums. Polar easterlies are dry, cold prevailing winds that blow from the east.
What is wind class 9 geography?
(b) Winds — Horizontal movements of the air from high pressure to low pressure areas are called winds. (c) Coriolis force — This force is created by the rotation of the earth as the winds in different belts deflect towards right in Northern hemisphere and to the left in Southern hemisphere.
What are the wind types in Class 7 wind?
- Permanent winds. The trade winds, westerlies, and easterlies are the permanent winds. …
- Seasonal winds. …
- Local winds.
What are local winds Upsc?
Name | Nature of wind | Place |
---|---|---|
Solano | Hot, moist wind | Sahara to the Iberian Peninsula |
Harmattan (Guinea Doctor) | Hot, dry wind | West Africa |
Bora | Cold, dry wind | Blows from Hungary to North Italy |
Mistral | Cold wind | The Alps and France |
What are the 3 types of winds?
- Primary Wind.
- Secondary Wind.
- Tertiary Wind.
What is called wind?
Air is constantly moving around the earth. This moving air is called wind. Winds are created when there are differences in air pressure from one area to another. In areas of high-pressure (sinking air), air at ground level spreads out, moving away from the high pressure.
What is wind answer?
Complete answer: In simple terms, the wind is nothing but moving air. The air movement is always from high pressure to low-pressure areas. … These are extremely steady winds that blow from subtropical high-pressure areas towards the equatorial low-pressure belt.
What are local winds Shaalaa?
Local winds are the winds that blow only in a particular locality for a short period of time. The effect of these local winds is experienced only in that particular area.
Is Chinook a local wind?
Chinook is the warm and dry local wind blowing on the leeward side or eastern side of Rockies (Prairies). Chinook is more common in winter and early spring from Colorado to British Columbia in Canada. The winds after descending through eastern slopes of the Rockies have warmed adiabatically.
Is monsoon A wind?
A monsoon is a seasonal change in the direction of the prevailing, or strongest, winds of a region. … Monsoons are most often associated with the Indian Ocean. Monsoons always blow from cold to warm regions. The summer monsoon and the winter monsoon determine the climate for most of India and Southeast Asia.
Which of the following is local wind?
Answer: Sea Breeze is the one of the following is a local wind.
Which is not local wind?
Explanation: Foehn is not a local wind.
What is a global wind?
Global winds are winds that occur in belts that go all around the planet (Figure below). Like local winds, global winds are caused by unequal heating of the atmosphere.
What does land breeze occur?
Land breeze: blowing breeze from land towards the sea is called a land breeze. They are formed during the night when sea water and land both lose heat, specific heat capacity of land being very low as compared to that of sea water, land loses heat energy fast and cools more rapidly as compared to the sea.
Which statement best describes how global or local winds are produced?
Like local winds, global winds are caused by unequal heating of the atmosphere. Winds blow on a diagonal over the surface due to Coriolis effect. Jet streams are fast-moving air currents high in the troposphere.
What causes winds by Brainly?
Answer: The wind is caused by differences in atmospheric pressure. When a difference in atmospheric pressure exists ,air moves from higher to the lower pressure area,resulting in winds of various speeds.
What do the arrows indicate winds?
The arrows indicate the direction the wind is going based on North being at the top of the screen and West being at the left. This is opposite of what a typical weather vane shows, because they point into the wind, rather than the direction it is headed. Take a “Northerly” wind, for example.
How does local wind affect climate?
The local winds moderates the climate of nearby areas with sudden increase or decrease in the temperature and humidity. In valleys of the mountains, two kinds of winds are particularly active – anabatic winds and katabatic winds.
How local winds affect the climate of a place?
The winds affect the climate because they create the hot and cold air which moves around. … The direction of local winds is determined by the daily temperature of variations. When winds blow from warm areas, they carry higher temperatures while winds blowing from cold areas carry lower temperatures.
What is wind and its types?
Wind is defined as the movement of air mass from an area of high pressure to an area of low pressure. In other words, the horizontal movement of the air in response to difference in pressure is known as wind. … Broadly, there are three types of winds – prevailing winds, seasonal winds and local winds.
How are winds named?
A wind is always named according to the direction from which it blows. For example, a wind blowing from west to east is a west wind. … This flow of air is wind. The difference in air pressure between two adjacent air masses over a horizontal distance is called the pressure gradient force.
