How does latitude affect weather
Places closer to the equator are warmer and places nearer the poles are colder
How does relief affect weather
Places on flat low lying land are warmer and places higher up are colder eg mountains
How does aspect affect weather
Places nearer the sea are mild and wet and places further from the sea are drier and temperatures are more extreme
