How to Make a ClimographHow to Make a Climograph
Amount of Precipitation (mm) Temperature in
degrees Celsius
Place Months along the bottom
Connect temperature dots
Make precipitation into a bar graph

Factors Affecting TemperatureFactors Affecting Temperature 1. 1. PPrecipitationrecipitation – determined by distance – determined by distance
from sea and prevailing windsfrom sea and prevailing winds
2. 2. AAltitudeltitude – the higher the altitude the colder – the higher the altitude the colder Top the of ski hills is way cooler than the
bottom Mt Washington 1,917 meters (12-13 degrees
cooler)
3. 3. DDistance from the seaistance from the sea – temperature is – temperature is moderated by water since land heats and moderated by water since land heats and cools more rapidlycools more rapidly
