Local Winds

What causes winds? How do local winds and global winds differ?

Review of Global Winds

Let's review what we learned last week!!!!

Multiple Choice

Coriolis Effect

• bands of high and low pressure found about every 30 degrees of latitude

• the curving of a path of a moving object from an otherwise straight path due to Earths rotation

• winds that blow from east to west between 60 and 90 degrees latitude in both hemispheres

• narrow belts of strong winds that blow in the upper troposphere

Multiple Choice

horse latitudes

• winds that blow from west to east between 30 and 60 degrees latitude in both hemispheres

• winds that blow from 30 degrees latitude almost to the equator in both hemispheres

• area around the equator where there is very little wind ("dull", "sluggish")

• area around 30 degrees latitude in both hemispheres where there is very little wind

Multiple Choice

westerlies

• winds that blow from west to east between 30 and 60 degrees latitude in both hemishpheres

• winds that blow from 30 degrees latitude almost to the equator in both hemispheres

• area around the equator where there is very little wind ("dull", "sluggish")

• area around 30 degrees latitude in both hemispheres where there is very little wind

Multiple Choice

Polar Easterlies

• bands of high and low pressure found about every 30 degrees of latitude

• the curving of a path of a moving object from an otherwise straight path due to Earth's rotation

• winds that blow from east to west between 60 and 90 degrees latitude

• narrow belts of strong winds that blow in the upper troposphere

Open Ended

Why are the horse latitudes and doldrums different from the other wind zones?

Let's Add Something I Forgot Last Week

OOPS

Multiple Choice

jet stream

• bands of high and low pressure found about every 30 degrees of latitude

• the curving of a path of a moving object from an otherwise straight path due to Earth's rotation

• winds that blow from east to west between 60 and 90 degrees latitude in both hemispheres

• narrow belts of strong winds that blow in the upper troposphere

Local Winds

Key Concept: Local winds are caused by the unequal heating of Earth’s surface within a small area.

• Local winds are winds that blow over a short distance. A cool breeze blowing in from the water over a beach is an example of a local wind.

• Unequal heating often happens near lakes and ocean coasts.

Multiple Choice

Local winds blow over:

• short distances

• long distances

• the poles

• the equator

Multiple Choice

What causes differences in air pressure?

• even heating of the Earth

• Even cooling of the earth

• uneven heating of the earth

• global warming

Multiple Choice

Is this a land or a sea breeze?

• land breeze
• sea breeze

Multiple Choice

What kind of breeze is this and when would it form?

• Land breeze - daytime
• Land breeze - nighttime
• Sea breeze - daytime
• Sea breeze - nighttime

Multiple Choice

mountain breeze

• cool mountain air moves down a mountain slope towards a valley

• warm air rises up a mountain slope from a valley

• cool land air flows to the ocean at night, causing warm ocean air to rise

• cool ocean air flows to land during the day, causing warm land air to rise

Multiple Choice

land breeze

• cool air moves down a mountain slope toward a valley

• warm air rises up a mountain slope from a valley

• cool land air flows to the ocean at night, causing warm ocean air to rise

• cool ocean air flows to land during the day, causing warm land air to rise

Multiple Choice

sea breeze

• cool mountain air moves down a mountain slope towards a valley

• warm air rises up a mountain slope from a valley

• cool land flows to the ocean at night, causing warm ocean air to rise

• cool ocean air flows to land during the day, causing warm land air to rise

Multiple Choice
