Weather is what’s happening outside.
Climate is a long-term average of the Weather.
experienced in a particular area over a long
period of time . The climate tells us how
hot, cold or wet it is likely to be in different
parts of the world at different times of year.
-the seasonal cycle: caused by the movement of earth around the sun
-El Nino: it is caused by interactions between the atmosphere and the ocean
-Thermohaline circulation (THC): moves water between the deep and surface ocean worldwide. The water moves mainly because of differences in density. Water that is more dense sinks below water that is less dense.
-The Madden–Julian oscillation (MJO)
-The North Atlantic oscillation (NAO)
-The Pacific decadal oscillation (PDO)
and many more.
The Thermohaline circulation or Global Ocean Conveyor
Map of the average temperature over 30 years. We can make these maps thanks to data records.
Climate models simulate the interactions of the atmosphere, oceans, and land surface so we can make predictions of future climate.
- The rotating tank lab will be used occasionally to illustrate different climate concepts.
