In what ways are land & sea breeze similar to Asian monsoon circulation
Similarities between
land & sea breeze are as follows:-
1) In land & sea breeze land &
sea/ocean is involved.
Here, land (but subcontinent or apart of the subcontinent) &
ocean/sea (never a lake or minor water body) is involved.
2)It is caused due to thermal contrast
between land & sea due to differential specific heat capacity of land &
water.
In Asian monsoon circulation, thermal contrasts during the different
seasons (especially summer & winter when contrasts are maximum) between
land & sea is it's cause, due to difference in specific heat capacity
between land & water.
3)In land & sea breeze both horizontal
& vertical heat transfers occur.
In Asian monsoon circulation, both horizontal & vertical heat
transfers occur.
4)In
land & sea breeze, cumulous cloud formation is encouraged by it's
circulation.
In Asian monsoon circulation, more than one type of cloud formation
occurs.
5) Day time sea breeze is directed from a
relatively cool high pressure sea (high pressure divergence) to a distinctly
warm land (low pressure convergence).
In Asian monsoon circulation,
during the summer monsoons the winds are on-shore directed from relatively high
pressure areas to warm land.Eg.-Macernes high over Indian ocean & heat low
over north-west India during south-west monsoon.
6) The oppositely directed land breeze occurs
at night when less energy is available with low pressure over the water body
& high pressure over land.
In Asian monsoon circulation, the
winter monsoon or winter season there is anticyclogenesis over land
resulting in off-shore winds.
Dissimilarities between land & sea
breeze are as follows:-
1)land or sea breeze is tertiary circulation
or local flow.
In Asian
monsoon circulation, it’s a global planetary circulation.
2) land & sea breeze is restricted to the
land close to the bank of the lake or the coastal area.
In Asian monsoon circulation, it affects a huge land masses.-Indian subcontinent
affected by south-west monsoon.
3)Velocity of sea breeze which is a part of
land-sea breeze circulation has a velocity of 4 to 7 meters per second.
In Asian monsoon circulation, velocity of jet stream which is an
important part of monsoon mechanism blows at a velocity of 110-184 Km/hr.
4) Land & sea breeze is a daily
phenomenon.
In Asian monsoon circulation, it’s seasonal phenomenon.
5) Land & sea breeze is not related to
floods 7 droughts in an area if it fails.
In Asian monsoon circulation, failure or excess will lead to droughts or
floods.
6)Land & sea breeze only forms due to
differential heating rate between land & sea.
In Asian monsoon circulation, it’s mechanism of formation is complex
including movement of westerlies,jet stream,ENSO circulation apart rom
differential heating of land & sea due to movement of sun.
7)Land & sea breeze encourages the
development of front.Eg.-sea breeze front.
In Asian monsoon circulation, allows no frontal development.
