Homework 6.4 (Fronts)

The cross section below represents a frontal boundary between two air masses. Arrows represent the direction of moving air masses. The type of front represented at the boundary between the cold air mass and the cool air mass is:

• an occluded front caused by a cold front overtaking a warm front

• an occluded front caused by a warm front overtaking a cold front

• a stationary front caused by a cold front overtaking a warm front

• a stationary front caused by a warm front overtaking a cold front

Base your answer to the following question on the cross section below and on your knowledge of Earth science. The arrows on the cross section represent the air movement along a weather front between two different air masses. The air masses are labeled. Which type of front is represented by this cross section?

• warm

• cold

• stationary

• occluded

Base your answer to the following question on the weather map below and on your knowledge of Earth science. Which weather condition is shown along the cold front?

• fog

• snow

• haze

• thunderstorms

Based on the information on the station model, the weather at this location in New York State is:

• partly cloudy and windy with blowing snow

• cloudy and windy with thunderstorms

• cloudy and calm with visibility of 2 miles

• partly cloudy and calm with an air temperature of 73°F

Base your answer to the following question on the station model diagram and on your knowledge of Earth science. What are the wind direction and the wind speed at this location?

• wind from the southeast at 15 knots

• wind from the northwest at 15 knots

• wind from the southeast at 25 knots

• wind from the northwest at 25 knots

The weather station model below shows some of the weather data for a certain location. What is the wind speed shown on the station model and which instrument is used to measure the wind speed?

• 15 knots, measured by a wind vane

• 15 knots, measured by an anemometer

• 25 knots, measured by a wind vane

• 25 knots, measured by an anemometer

The station model below shows several weather variables recorded at a particular location. What was the most likely dew point at this location?

• 32°F

• 40°F

• 61°F

• 70°F

A weather station model is shown. The barometric pressure indicated by this station model is
