Climate refers to the overall weatherconditions prevailing in a certain region overa long period of time, which may be in
decades or centuries.
Climate
What is climate?
1
Climate is determined by averaging theweather of a region over a long period of
time, such as 30 years.

1. Tropical Climate
Kinds of Climate
1
The tropical zonethe region betweenlatitudes 30N and30Sreceive themost solar radiationbecause the sunshines almost directly
over these areas. Dry / sunny or wet /
rainy

Temperate Climate
Kinds of Climate
1
Between the tropicalzones and the polarzones are thetemperate zones.
Temperatures hereare moderate.
Also called
midlatitude climate.
Spring, summer,autumn and winter

The polar zonesextend from 66.5Nand 66.5S latitudeto the poles. Solar
radiation hits thesezones at a low angle,spreading energy
over a large area.
Polar Climate
Kinds of Climate
1
Polar regions are never warm.

It takes a lot more heat to increase thetemperature of water than it takes to increase
the temperature of land.
Other Factors
Large Bodies of Water

In addition, water must give up more heatthan land does for it to cool.

Large bodies ofwater can affectthe climate of
coastal areas byabsorbing orgiving off heat.

This causes many coastal regions to be warmerin the winter and cooler in the summer thaninland areas at similar latitude.

Ocean currents affect coastal climates.
Ocean Currents
What is climate?
1
Warm currents begin near the equator and
flow toward higher latitudes, warming theland regions they pass.

At the samelatitude, theclimate iscolder in themountainsthan at sealevel.
Mountains
What is climate?
1
When radiation from the Sun is absorbed byEarths surface, it heats the land.

Mountains
What is climate?

Heat fromEarth thenwarms theatmosphere.
BecauseEarths
atmosphere
gets thinner at higher altitudes, the air in themountains has fewer molecules to absorb heat.

Streets, parking lots, andbuildings heat up, in turnheating the air.
Cities
What is climate?
1
Air pollution traps this
heat, creating what isknown as the heat-island effect.
Temperatures in a citycan be 5C higher than insurrounding rural areas.
