Energy Balance

Get your notebook or a piece of paper.

Coördinaten

Om een locatie te kunnen aanwijzen heb je twee getallen nodig: de breedtegraad en de lengtegraad (longitude.

Longitude

Latitude

Where is an energy surplus?

1. Low latitude
2. Middle latitude
3. High latitude

Is an energy surplus a positive or a negative thing?

Negative

Enhanced greenhouse effect

Positive

Renewable energy -->
Solar Panels

What is the difference between an energy deficit and an energy surplus?

Energy deficit (Low)
Less energy than needed.
More outgoing than incoming energy

Energy surplus (High)

More energy than needed.

More incoming than outgoing energy.

Global warming

Global warming is caused by the enhanced greenhouse effect. The greenhouse gases reflects heat coming from the surface of the earth back towards the earth. This causes the atmosphere to increase in temperature

Temperatures above land and sea

Land gets warmer than water but it gets colder than water too.

Land heats up and cools down faster than water.

What effect does this have on for example the Netherlands?

In coastal areas, temperature differences are small.

(Flora and Fauna)

Pressure: High pressure & Low pressure

High pressure area

Sinking air due to low temperatures.

Summer: Hot & Dry         Winter: V Cold & Dry

+ / H / Maximum

Air molecules are close to eachother --> heavy --> sinking

Low pressure area

Rising air due to high temperatures.

Summer: Hot & Rain          Winter: Cold & Snow

- / L / Minimum

Air molecules are further away from eachother --> not as heavy --> rising

Global wind patterns

What is Buys Ballot's Law?

1. Air moves from H --> L

2. In the northern hemisphere the wind has a deviation to the right, in the southern hemisphere a deviation to the left (as if the wind is in your back when you're standing on the equator).
