I learned that monsoon is traditionally defined as a
seasonal reversing wind accompanied by corresponding changes
in precipitation,but is now used to describe
seasonal changes in atmospheric circulation and precipitation associated with
the asymmetric heating of land and sea.Usually, the term monsoon is used to
refer to the rainy phase of a seasonally-changing pattern, although technically
there is also a dry phase. Monsoons may be considered as large-scale sea breezes,
due to seasonal heating and the resulting development of a thermal low over
a continental landmass. They are caused by the larger amplitude of the seasonal
cycle of land temperature compared to that of nearby oceans. This differential
warming happens because heat in the ocean is mixed vertically through a
"mixed layer" that may be fifty metres deep, through the action of
wind and buoyancy-generated turbulence,
whereas the land surface conducts heat slowly, with the seasonal signal
penetrating perhaps a metre or so. There are two monsoons that we experience
here in the Philippines; the northeast monsoon and southwest monsoon. The
Northeast monsoon locally known as "Amihan". It affects the eastern
portions of the country from October up to late March, starts over Siberia as a
cold, dry air mass but gathers moisture as it travels across the Pacific Ocean
before reaching the eastern sections of the Philippines is characterized by
widespread cloudiness with rains and showers. The North Pacific Trades
gradually replaces the NE Monsoon in March, appears in all seasons and blows
dominantly from March to April, giving strong convective activity. The
southwest monsoon locally known as "Habagat", it affects the country
from July to September, is very warm and humid, occurs when warm moist air. I want to know more about how they
were formed and how they affect one place as they occur. I would like to
research on how we can lessen the effect it may brought. I can apply my
learning and insights in my daily living for example decide about our outings,
I can avoid the time when they are usually experienced to prevent unnecessary
things to happen.
