Dynamic Climate
An overview of Climate Oscillations
WHAT is a Climate Oscillation?
• Climates are long-term weather patterns.• Climates are a product of
– Latitude, – Altitude, – Proximity to Water, – Location and distribution of nearby Highlands, and – Nearby Ocean Currents.
• Which of these are static? • Which of these are dynamic?
Thermohaline Circulation: The Global Conveyor Belt
How thermohaline circulation runs
How Thermohaline Circulation works
How the Thermohaline affects the atmosphere.
Thermohaline Circulation, as viewed from the North Pole
What happens in the Antarctic
What can happen? (cont.)
The global conveyor belt thermohaline circulation is driven primarily by the formation and sinking of deep water.
When the strength of the haline forcing increases due to excess precipitation, runoff, or ice melt the conveyor belt will weaken or even shut down.
The variability in the strength of the conveyor belt will lead to climate change in Europe and it could also influence other areas of the global ocean.
So how does it affect climate?

So what present Climate Oscillations have been noted?
• El Niño Southern Oscillation (ENSO)
• North Atlantic Oscillation (NAO)
• Arctic Oscillation (AO)
• Pacific Decadal Oscillation (PDO)
El Niño Southern Oscillation (ENSO)
During El Niño, sea-surface temperatures in the eastern equatorial Pacific are warmer than usual (top), while during La Niña the same region is cooler.
