Low-pressure systems
This type of pressure system forms when air converges at the surface and rises, leading to clouds and precipitation.
What is a cyclone )or depression or low-pressure system)?
A high-pressure system is also called this.
What is an anticyclone?
Hurricanes are a type of this weather system that forms over warm ocean waters.
What is a low-pressure system (tropical cyclone)?
The ITCZ is found near this line around the Earth.
What is the equator?
A large body of air with uniform temperature and humidity is called this
What is an air mass?
These weather conditions are typically associated with a low-pressure system.
What are cloudy skies, rain, strong winds, and unstable weather?
Name two weather conditions typically found in high-pressure systems
What are clear skies and calm winds (or dry weather)?
The calm, clear center of a hurricane is called this.
What is the eye?
The ITCZ forms when trade winds from both hemispheres do this.
What is converge?
Tropical Maritime (mT) air has these characteristics.
What is warm and moist?
A low-pressure system often forms along this type of boundary where air masses meet.
What is a front (especially the polar front)?
High-pressure systems often form in these regions of the globe.
What are subtropical regions?
Name two weather conditions caused by hurricanes.
What are strong winds and heavy rain?
The ITCZ shifts north and south with this.
What is the seasonal movement of the sun?
Cold fronts bring these weather conditions.
What are sudden temperature drops and heavy rain?
This type of circulation occurs in the Northern Hemisphere, while the other occurs in the Southern Hemisphere?
What are clockwise and anti-clockwise circulations?
This high-pressure system influences the Caribbean dry season.
What is the Azores High?
Hurricanes form over oceans at least this warm.
What is 26°C?
This is a typical weather condition in the ITCZ.
What is heavy rainfall and thunderstorms?
Fronts form when these meet
What are two different air masses?
Low-pressure systems form when this happens to air at the surface.
What is air rises and forms clouds?
A high-pressure system where air sinks and spreads out at the surface is called this.
What is an anticyclone?
Hurricanes spin because of this effect of the Earth
What is the Coriolis effect?
When the ITCZ moves north in summer, this happens in the Caribbean.
What is more rain and wet weather?
This type of front forms when a warm air mass moves over a cold air mass, often causing light rain and drizzle.
What is a warm front?
