CLIMATE DRIVERS (SYNOPTIC SCALE) Flashcards
It is the boundary between two air masses that has different characteristics.
FRONTS
What changes are the indicator of fronts?
SHARP T
The type of a synoptic climate driver that possesses
different combinations of humidity and temperature.
AIR MASSES
What are the different types of fronts?
Cold Front
Warm Front
Stationary Front
Occluded Front
what are the six (6) types of air masses?
Maritime Continental Equatorial, Tropical Polar Arctic
During Habagat, what air mass brings warm and moist
conditions to the country?
Maritime Equatorial (mE)
The country is only affected by the ______?
Tail-end of a cold front.
During Amihan, what air mass brings cold and dry conditions to the country?
Continental Polar (cP)
Monssoen(Dutch) means?
Time of the year
Why monsoon is important?
Because most of the worlds population relies on monsoon as irrigation for their crops.
What is monsoon?
Refers to prevailing wind shifts of about 120° between January and July.
What is the average frequency of prevailing
wind?
greater than (>) 40%
Wind is coming from the NE and occurs during November to March.
Northeast Monsoon (Amihan)
Wind is coming from the SW and occurs during June to September.
Southeast Monsoon (Habagat)
Brings cold and dry air from continental Polar (cP) air mass and brings rain over the eastern part of the country.
Amihan
Brings warm and moist air from maritime Equatorial (mE) air mass and the perfect ingredient to produce
thunderstorms and tropical cyclones (TCs).
Habagat
Who created Modified Corona Classification
Created by Father J. Corona in 1921.
What are the four (4) types of climate?
Type 1: Maximum rain during Jun to Sep
Type 2: Maximum rain during Dec to Feb
Type 3: No pronounced maximum rain period
Type 4: Rainfall is distributed evenly throughout the year.
What is Modified Corona Clasification?
It is based on the on the average monthly rainfall of
a certain area.
Why is it called semi-permanent?
Because it migrates through the latitude just like airmasses.
What is Coriolis Effect?
It is is a pseudo-force that is created due to the rotation of the Earth.
It’s the pressure systems present over a certain area for a period of time and the explanation on why there are areas with deserts and rainforests.
Semi-Permanent High & Low
Describe the movement of TC
80% of its movement is dependent on the prevailing environmental winds.
The Australian Meteorologist who pioneered in naming tropical cyclones.
Clement Wragge
What are the hazard of a TC?
Storm surge Meteotsunamis Strong & High Winds rainfall/Flooding Lahar/Mudflow/Landslide
What are the positive impact of TC?
Power & Water source
Stability of Sea Surface
Natural Crop Irrigation
Minimize Air Pollution
