Opening · a definition

Local winds refer to winds blowing due to regional pressure & temperature differences, generally covering a small area. Eg - Sirocco, Berg, Chinook etc.

Body · points and prose

Diagram
[Map of the world with marked local winds] - North America: Chinook, Blizzard - Europe: Foehn, Buran - Asia: Buran, Karaburan - Africa: Sirocco, Gibli, Khamsin, Harmattan - South America: Zonda, Yoma - South Africa: Berg - Australia: Brickfielder, Norwester - Map: Major local wind patterns

These winds have multiple impacts on the regions the blow across.

WindRegionImpact
(1) ChinookOver rockies (N. Am.)→ warm winds
hence melt the snow in USA plains
↳ known as snow eater
(2) FoehnOver Alps (Switzerland)→ same impact as Chinook (European snoweater)
(3) SiroccoOver Mediterranean→ Takes sand from Sahara & moisture from mediterranean
↳ cause "Blood rain" in S. Europe.
(4) BlizzardCanada→ cold winds
→ Bring snow from polar regions into Canada
(5) Loo, Zonda, Brickfielder, Norwester(India)
(S. Am.)
(Australia)
(NZ)} all of these are very warm winds create excessively high temperature during summer months.

| (6) Harmattan & Berg | W. & S. Africa | → also known as Doctor winds ↳ bring drier conditions & stop rainfall (offshore) treating diseases |

Thus local winds have multiple impacts → climate, rainfall, economy, lifestyle etc. and are thus important for us to understand.
