Factors affecting Temperature [Date]

Today I will:

- Understand the four different factors which influence the temperature

Weather is a phenomena occurring in the atmosphere at any given time. It can

change quickly.

Climate refers to the average atmospheric

conditions over longer periods of time.

Latitude or distance from the equator

Temperatures drop the further an area is from the

equator due to the curvature of the earth.

In areas closer to the poles, sunlight has a larger area of atmosphere to pass through

and the sun is at a lower angle in the sky. As a result,

more energy is lost and temperatures are cooler.

The presence of ice and snow nearer the poles causes a higher albedo, meaning that more solar energy is

reflected, also contributing to the

cold.

2. Aspect In the Northern

Hemisphere, south facing slopes are warmer as they receive far more

sunlight than north facing ones and they are

sheltered from the wind.

3. Altitude or ReliefLocations at a higher altitude have colder temperatures.

Temperature usually decreases by 1°C for every 100 metres in altitude.

Mt Kilimanjaro is 5895m

Maximum Temperature in Moshi is 26⁰C. Moshi is located 800m

above sea level.

What is the temperature at the top of the mountain?

Temperature usually decreases by 1°C for every 100 metres in

altitude.

4. Distance from the sea- Oceans heat up and cool down much more slowly than land. This

means that coastal locations tend to be cooler in summer and warmer in winter than places inland at the same latitude and

altitude.

- A warm ocean current called the North

Atlantic Drift keeps Britain warmer than it

should.

- Our prevailing wind comes from the South West and so they bring

warmth from the Atlantic.
