Weather Basics
What is the condition of the atmosphere at a certain place and time?
weather
High-pressure systems usually bring this type of weather.
clear, sunny weather
Which front forms when a cold air mass pushes under a warm air mass?
cold front
A large body of air with similar temperature and humidity is called this.
air mass
Climate describes weather patterns over a ______ period of time.
long
What tool measures air temperature?
What is a thermometer?
Low-pressure systems are often associated with these conditions.
clouds and storms
Which front forms when a warm air mass slides over a cold air mass?
warm front
A continental air mass forms over this type of surface.
land
Ocean currents move this around Earth.
heat (thermal energy)
Water vapor in the air is called this.
humidity
Air in a high-pressure system is generally doing this.
What is sinking
Which front forms when neither air mass moves?
stationary front
A maritime air mass forms over this type of surface.
water
Warm ocean currents generally make nearby coastal climates this.
warmer
The amount of water vapor in the air compared the air temperature?
Relative Humidity
Air in a low-pressure system is generally doing this.
rising
Which front forms when a cold front catches up to a warm front?
occluded front
A maritime tropical air mass is best described as this.
warm and humid
The Gulf Stream is an example of this type of current.
warm ocean current
The temperature at which water vapor condenses into liquid water is called this.
dew point
Rising air cools and forms clouds because of this process.
condensation
This type of front is most likely to produce strong thunderstorms.
cold front
A continental polar air mass is best described as this.
cold and dry
Explain how ocean currents can affect weather and climate.
they transfer heat, making some areas warmer or cooler and affecting precipitation patterns
