Meteorology Test 2- Saturday

Which of the following describes an air mass with the symbol mT?

• cold and wet because it forms over a cold ocean

• cold and dry because it forms over an area of cold land

• warm and wet because it forms over a warm ocean

• warm and dry because it forms over an area of warm land

Answer explanation

The symbol mT stands for maritime Tropical, indicating an air mass that is warm and wet, as it forms over warm ocean waters. This distinguishes it from other air masses that are either cold or dry.

What type of air mass forms over Mexico and affects the southwestern United States?

• A) maritime polar since the cold air mass forms over water

• B) maritime tropical because the warm air is humid

• C) continental polar because the warm air mass is dry

• D) continental tropical since the warm air is dry

Answer explanation

The correct answer is D) continental tropical since the warm air is dry. This air mass forms over land in Mexico, bringing warm and dry conditions to the southwestern United States.

Which air mass will bring cold, dry air from Canada to the United States?

• A) maritime polar

• B) maritime tropical

• C) continental polar

• D) continental tropical

Answer explanation

The continental polar air mass originates from Canada, bringing cold and dry air to the United States. This distinguishes it from maritime air masses, which are moist, and tropical air masses, which are warm.

What weather would result from a rapidly moving cold air mass that collides head on with a slow moving warm air mass?

• heavy rains with possible thunderstorms

• heavy rain and/or snow for many days

• gentle rain that can last for days

• a mix of cloudy skies and gentle rains lingering for days

Answer explanation

When a rapidly moving cold air mass meets a slow-moving warm air mass, it forces the warm air to rise quickly, leading to heavy rains and possible thunderstorms due to the instability created in the atmosphere.

An air mass forms over the Gulf of Mexico/Atlantic Ocean and moves northeast into Georgia. What weather conditions are likely to prevail in Georgia?

• cool and dry with high pressure

• cool and humid with high pressure

• warm and dry with low pressure

• warm and humid with low pressure

Answer explanation

An air mass from the Gulf of Mexico/Atlantic Ocean is typically warm and humid. As it moves into Georgia, it brings these characteristics, leading to warm and humid conditions, often associated with low pressure.

Hurricanes, tornadoes, and thunderstorms have which of the following characteristics in common?

• formation in a high-pressure system

• formation in a low-pressure system

• they all create large amounts of storm surge

• the each have a calm area at the storm’s center

Answer explanation

Hurricanes, tornadoes, and thunderstorms all form in low-pressure systems. This is a key characteristic that distinguishes them from other weather phenomena, as low pressure allows for the rising of warm, moist air, leading to storm development.

The maps below show a front as it moves east across the United States. Which of these describes the weather change that can be expected for Amarillo, Texas?

• The cold front will bring cooler temperatures and possibly snow because of the low pressure

• The cold front will bring cooler temperatures that will increase condensation to create thunderstorms and rain

• The cold front will slow down when it hits the warmer temperatures because it can't push the warm air out of the way.

• The low pressure system will cause the temperature to decrease and rain for a few days.

Answer explanation

The correct choice indicates that the cold front will bring cooler temperatures, which can lead to increased condensation, resulting in thunderstorms and rain. This aligns with typical weather patterns associated with cold fronts.

Which city will experience a drop in temperature in the next day or so?

• Billings because the cold front has already passed through moving south

• Denver because it if behind the cold front as it moves south

• Minneapolis because it is in front of the cold front that is moving southeast

• Atlanta because it is close to the low pressure that is moving north

Answer explanation

Minneapolis will experience a drop in temperature because it is located in front of the cold front moving southeast, which typically brings cooler air. The other cities are either behind the front or not affected.

What type of weather is indicated by the symbol 'L' on the map?

• Low Pressure- heavy rain or storms

• High Pressure- Light rain

• Low Pressure- sunny and clear skies

• High Pressure- heavy rain or storms

Answer explanation

The symbol 'L' on a weather map indicates low pressure, which is typically associated with heavy rain or storms. This is why the correct answer is 'Low Pressure- heavy rain or storms'.
