Q2 - Landmasses & Bodies of Water

What will happen to a typhoon when it landfalls or hits landmasses?

• The wind capacity becomes stronger.

• The wind speed becomes faster.

• The wind speed becomes stronger.

• The wind speed becomes weaker.

Merla noticed that when typhoons came from the west, they barely get affected by such weather systems. But when typhoons originate from the east, they would almost always be dealing with strong winds and sometimes floods. Their village in General Santos City is sandwiched by a mountain range 2 kilometers from the west and by the sea, which is about a kilometer away, what can explain her observations?

• Cold air produced by trees from the mountains weakens the incoming typhoons headed towards the village.

• Merla is mistaken as typhoons in tropical countries would always follow a west to east route.

• Mountains have the ability to deflect bodies of air, thus, Merla’s village is not affected by typhoons from the west.

• Typhoons cannot possibly originate west of their village as there is no body of water from that direction.

On October 18, 2010, Typhoon Juan made landfall over Isabela. By noon of the same day, it passed through the Sierra Madre Mountain Range. Later during the day, the typhoon hit the South China Sea. If you are to predict what will happen to the typhoon given these situations, what will be the most likely prediction?

• Typhoon Juan Is expected to gain intensity as it approaches the Sierra Madre Mountains. It will eventually weaken and dissipate over the South China Sea.

• Typhoon Juan is expected to weaken as it passes the Sierra Madre Mountains. When it hits the South China, it is expected to gain intensity.

• Typhoon Juan will continue to gain strength as it passes through the different areas within the Philippine Area of Responsibility.

• Typhoon Juan will weaken and eventually dissipate as it goes out of the Philippine Area of Responsibility.

How do landmasses affect typhoon?

• Landforms lessen the strength of typhoons whenever the winds impact them.

• Landforms increases the strength of typhoons whenever the winds impact them

• Landforms lessen the strength of typhoons anytime the winds impact them.

• Landforms increases the temperature as it goes up from a high mountain.

How do bodies of water affect typhoon?

• Typhoon gain energy from warm ocean water and lose energy over cold water.

• Typhoon gain energy from cold ocean water and lose energy over warm water.

• Typhoon is affected by bodies of water because its wind speed was stronger after it made landfall in the island or mountain.

• Typhoon is affected by bodies of water because its wind speed was lessened before it made landfall in the island or mountain, but it increases after passes through island.

Precipitation usually falls on this side of a mountain.

• Eastward Side

The following happens in the leeward side EXCEPT____.

• Temperature decreases

• Temperature increases

• Little or no precipitation

• Sinking air

Which of the following Best describes the cause of a rain shadow?

• A decrease in temperature along with condensation of water vapor

• An increase in temperature along with condensation of water vapor

• A decrease in temperature along with the evaporation of water vapor

At which setting will orographic lifting occur?

• a flat plain

• a large forest

• a mountain range

• a sandy dessert

An example of orographic clouds would be

• clouds forming over warm ocean current

• clouds forming on the windward slope of a mountain

• Clouds forming behind a jet air plane

• Clouds formed by surface heating
