13ESS ENSO pt 1

Trade winds at the equator move from:

• East to West

• West to East

This layer of water is warm because sunlight can penetrate into it without being fully absorbed:

• Mixed Layer

• Deep Layer

This latitude receives direct sunlight spread over a small area so it is more intense:

• Poles

• Equator

• Mid Latitudes

The ENSO climate cycle is driven by processes in this ocean basin:

• Atlantic Ocean

• Southern Ocean

• Pacific Ocean

• Indian Ocean

In ENSO Normal years the West side of the Pacific is:

• Warm due to warm water being pushed here by trade winds

• Cold due to deep water upwelling to replace warm water pushed away by trade winds

In ENSO Normal years the East side of the Pacific is:

• Warm due to warm water being pushed here by trade winds

• Cold due to deep water upwelling to replace warm water pushed away by trade winds

The movement of cold water from the deep layer up into the mixed layer is called:

• Upwelling

• Downwelling

Hot ocean water causes air temperatures to:

• Increase

• Decrease

• Stay the same

Cold ocean water causes air temperatures to:

• Increase

• Decrease

• Stay the same

Hot air becomes less dense so it will:

• Rise upwards creating Low pressure on the ground/water

• Sink downwards creating High pressure on the ground/water
