PHNAVY BMC Lecture 7-Weather Systems Affecting the Philiippine

Multiple Choice

What is the primary characteristic of a tropical cyclone in the Philippines?

• a) Low-pressure system

• b) High-pressure system

• c) Moderate temperature

• d) Dry conditions

Answer: a) Low-pressure system

Tropical cyclones are characterized by low-pressure systems that form over warm ocean waters. They bring strong winds, heavy rainfall, and potentially destructive storm surges.

Multiple Choice

Which of the following weather phenomena brings the most heavy rainfall and strong winds to the Philippines?

• a) Monsoons

• b) ITCZ

• c) Shear line

• d) Easterlies

Answer: a) Low-pressure system

Tropical cyclones are characterized by low-pressure systems that form over warm ocean waters. They bring strong winds, heavy rainfall, and potentially destructive storm surges.

Multiple Choice

The ITCZ (Intertropical Convergence Zone) is known for __________.

• a) Low-pressure conditions

• b) High-pressure conditions

• c) Dry and sunny weather

• d) Cold temperatures

Answer: a) Low-pressure conditions

The ITCZ is a belt of low-pressure that encircles the Earth near the equator. It is characterized by converging trade winds, ascending air, and a high likelihood of precipitation.

Multiple Choice

What is the primary characteristic of a ridge of high-pressure area in the Philippines?

• a) Low-pressure system

• b) High-pressure system

• c) Intense thunderstorms

• d) Frequent tornadoes

Multiple Choice

Which weather phenomenon is characterized by a line of abrupt changes in wind direction and temperature?

• a) Shear line

• b) Easterlies

• c) ITCZ

• d) Monsoons

Answer: a) Shear line

A shear line is a weather phenomenon marked by a line of abrupt changes in wind direction and temperature. It often brings unstable weather conditions, including thunderstorms and heavy rainfall.

Multiple Choice

What is the prevailing wind direction associated with the easterlies in the Philippines?

• a) From west to east

• b) From east to west

• c) From north to south

• d) From south to north

Answer: a) Shear line

A shear line is a weather phenomenon marked by a line of abrupt changes in wind direction and temperature. It often brings unstable weather conditions, including thunderstorms and heavy rainfall.

Multiple Choice

What is the process by which water vapor in the atmosphere condenses into liquid or solid forms and falls to the ground?

• a) Evaporation

• b) Transpiration

• c) Precipitation

• d) Condensation

Multiple Choice

Which of the following is NOT a type of precipitation?

• a) Rain

• b) Snow

• c) Fog

• d) Hail

Multiple Choice

El Niño is characterized by _____________.

• a) Warmer-than-average ocean temperatures in the Pacific

• b) Cooler-than-average ocean temperatures in the Pacific

• c) Dry and hot conditions in the Philippines

• d) Intense thunderstorms and typhoons

Multiple Choice

La Niña is characterized by __________.

• a) Warmer-than-average ocean temperatures in the Pacific

• b) Cooler-than-average ocean temperatures in the Pacific

• c) Dry and hot conditions in the Philippines

• d) Intense thunderstorms and typhoons
