CLIMATE DRIVERS (SYNOPTIC SCALE) Flashcards
SYNOPTIC SCALE
Air Masses
Monsoons
Semi-permanent highs and low
Tropical Cyclones
Type of a synoptic climate driver that possesses different combinations of humidity and temperature and can be classified based on humidity (maritime &
continental) or based on temperature (equatorial, tropical, polar, & arctic)
Air Masses
What is the effect of AIR MASS in the Philippines?
During Habagat, a maritime Equatorial (mE) air mass
brings warm and moist conditions to the country.
During Amihan, a continental Polar air mass (cP) brings cold and dry conditions to the country.
It is the boundary between two air masses that has
different characteristics.
Fronts
It is the indicator of fronts.
Sharp T changes
What are the different types of fronts?
Cold Front
Warm Front
Stationary Front
Occluded Front
What is the effect of Fronts in the Philippines?
The country is only affected by the tail-end of a cold front. A southern extent of a passing cold front over
Taiwan or Japan and it brings cool northeasterly
winds with precipitation across eastern Philippines
Also known as Monssoen (Dutch) which means
‘time of year’.
Monsoons
it refers to prevailing ____________ between __________
Wind shifts of about 120°
January and July
Average frequency of prevailing
wind is _____
greater than (>) 40%.
Locally known as “HABAGAT” the wind is coming from the SW and a perfect ingredient to produce
thunderstorms and tropical cyclones (TCs).
SOUTHWEST MONSOON
Southwest monsoon occurs during what month?
June to September.
Brings ____________ from ___________ air mass.
warm and moist air maritime Equatorial (mE)
Locally known as “AMIHAN” the wind is coming from the NE and brings rain over the eastern
part of the country.
NORTHEAST MONSOON
Brings ___________ from ______________ air mass and Occurs during __________.
cold and dry air
continental Polar (cP)
November to March
MODIFIED CORONA CLASIFICATION is created by whom in what year?
Created by Father J. Corona in 1921.
Based on the average monthly rainfall of
a certain area. It has four climate types:
What types of climate has no pronounced maximum
rain period?
Type 3
What types of climate has a maximum rain during June to September?
Type 1
What types of climate has the Rainfall is distributed evenly throughout the year?
Type 4
What types of climate has a maximum rain during December to February?
Type 2
SEMI-PERMANENT H’s & L’s
Pressure systems present over a certain area for a period of time.
Why is it called semi-permanent?
because it migrates through the latitude just like airmasses.
It is a pseudo-force that is created due to the rotation of the Earth.
Coriolis Effect
