Global Patterns and Local Weather

What causes the local weather that impacts our daily lives?

• Interactions between radiation from the sun, Earth's large ocean, different types of landscapes, and motion in space

• Earth's rotation around the sun

• A flat dry landscape and an untilted axis

• The Coriolis Effect

What creates global circulation patterns on Earth?

• Uneven heating of Earth's surface

• The Coriolis Effect

• The presence of air masses

• The rotation of Earth on its axis

What are convection currents?

• Air currents that move from the equator towards the poles and back

• Narrow bands of strong winds high up in the atmosphere

• The place where two air masses meet

• Large bodies of air that extend across large areas of Earth

What is the Coriolis Effect?

• The deflection of winds from a straight-line path due to Earth's rotation

• The meeting point of two air masses

• The movement of air masses by jet streams

• The creation of global circulation patterns

What is a front in meteorological terms?

• The place where two air masses meet

• A narrow band of strong winds high up in the atmosphere

• A large body of air with uniform characteristics

• A cyclonic system

How are air masses moved around the globe?

• By narrow bands of strong winds such as the jet streams

• By convection currents

• By the Coriolis Effect

• By global circulation patterns

What happens to air in the Northern Hemisphere due to the Coriolis Effect?

• It veers to the right

• It veers to the left

• It moves in a straight line

• It forms cyclonic systems
