AIR MASSES AND
FRONTS
AIR MASS
Ang AIR MASS ay isang kumpol ng hangin na may
halos parehong temperatura at halumigmig
(humidity). Nakukuha ng isang air mass ang mga
katangiang ito habang nasa ibabaw ng bahagi ng
lupa o tubig na tinatawag na source region. Kapag
ang isang air mass ay nananatili sa isang lugar sa
loob ng ilang araw o mahigit pa, nakukuha nito ang
temperatura at humidity ng lugar.
MGA SOURCE REGION NG
MGA AIR MASS
ARCTIC AIR MASS
Napakalamig na hangin na nabubuo sa Arctic at Antarctic
TROPICAL AIR MASSNabubuo sa mga lugar na mababa
ang latitude at katamtaman ang
init
POLAR AIR MASS
Malamig na hangin na nabubuo sa mga lugar na nasa mataas na latitude
EQUATORIAL AIR MASSMainit na hangin na nabubuo
malapit sa Equator
MARITIME AIR MASS
Maalinsangang hangin na nabubuo sa ibabaw ng dagat
CONTINENTAL AIR
MASSTuyong hangin na nabubuo sa ibabaw ng lupa
ABBREVIATIONS
cP: cold, dry air mass
mP: cold, moist air mass
cT: warm, dry air mass
mT: warm, moist air mass
• A lowercase letter describes the amount of
moisture in the air mass: m for maritime
(moist) and c for continental (dry).
• An uppercase letter describes the heat of
the air mass: E for equatorial, T for
tropical, P for polar, A for Arctic or Antarctic.
• A lowercase letter describes the relationship
between the air mass and the
earth: k signifies that the air mass is colder
than the ground below it, while w describes
an air mass that is warmer than the ground
below it.
AIR MASS SA WEATHER MAPS
FRONTS
Paggalaw ng hangin na naghihiwalay sa dalawang
magkaibang uri ng air mass.
Nabubuo kapag ang isang uri ng air mass ay
pumasok sa lugar na saklaw ng ibang uri ng air mass.
Ang isang uri ng hangin ay kadalasang mas mabigat
kaysa sa iba, at may ibang temperatura at lebel ng
humidity.
Ang pagsasalubong ng hangin ay nagdudulot ng sari-
saring lagay ng panahon: ulan, init, lamig, at
mahangin na panahon .
COLD FRONT
Ang cold front ay ang transition zone kung saan ang isang malamig na
air mass ay pinapalitan ang isang mainit na air mass. Ito ay karaniwang
gumagalaw galling kanluran (west) patungong silangan (east). Mas
mabilis ang cold front kaysa sa warm front dahil mas maraming
molecules ang malamig kaysa sa mainit na hangin. Ito ay kadalasang
nagdadala ng ulan at bagyo.
WARM FRONT
Ang warm front ay nangyayari kapag ang isang mainit na air mass ay
pinapalitan ang isang malamig na air mass. Ito ay karaniwang gumagalaw
galing timog-kanluran (southwest ) patungong hilagang-silangan (northeast ).
Ito ay karaniwang nagdadala ng matiwasay at maaliwalas na panahon.
