Weather Flashcards
How does latitude affect climate?
- Temperatures generally decrease the further north you go because the sun’s rays are less concentrated further away from the equator.
- It’s colder in northern Scotland because there is more atmosphere for the sun’s rays to pass through.
How does altitude affect climate?
- Wind speeds increase as altitude increases.
- Temperatures decrease 1C for every 100 meters gained in height.
How does continentality affect climate?
- The North Atlantic Drift keep. the temperatures warmer on the west coast than on the east coast of the UK.
- Places further inland have a greater annual range in temperature due to distance from the effects of the oceans.
- Places closer to the sea have warmer/milder winters and cooler summers because oceans heat up slowly in summer and cool slowly in winter.
How does aspect affect climate?
- In the northern hemisphere south facing slopes can be warmer because they face the sun.
- North facing slopes are shaded from the sun and are therefore cooler.

Give an answer to an exam question about the impacts of polar continental air mass
Will bring cold air, leading to snow and roads being blocked. Schools may have to move to remote learning. Once the snow melts, rivers could flood with the extra water. Sledge and skis sales will increase as people make the most of the snow. Increase in heating bills as people will need to get warm in homes. Increase in death rate for the elderly who may struggle with the cold temperatures and access in the snow.
