HOW DO WE STUDY CLIMATE? MAKING & ANALYSING CLIMOGRAPHS

HOW DO WE STUDY CLIMATE? โ ข To study the climate we use climographs. Over the months we see how it evolves with the temperatures represented by a line and precipitations with bars.

HOW DO WE ANALYSE A CLIMOGRAPH? In order to analyse a climograph we must take into account the main features on it:

• Temperatures • Precipitations

HOW DO WE ANALYSE A CLIMOGRAPH? 1. TEMPERATURES: Shown as a line that joins monthly average temperatures.

– Average temperature: The first thing you have to do is find, approximately, the annual average temperature. Remember all averages over 20ºC are hot or torrid climates, between 20 and 0ºC temperate climates, below 0ºC cold climates.

– Atmospheric temperature range: It is the difference between the hottest month and the coldest one. Tropical climates have small ranges (less than 5ºC) Temperates, specially continental ones, have bigger ranges. You have to identify if there are seasons or not. Tropical climates have no seasons.

HOW DO WE ANALYSE A CLIMOGRAPH? 2. PRECIPITATIONS: Precipitations are shown as blue bars. Each bar represents the total amount of rain measure in millimeters (mm) by square meter.

– Total precipitations: First we must add all monthly precipitations. An amount over 1.000 mm must be considered a rainy/humid climate, between 1.000 mm and 300 mm medium, below 300 mm it may be arid or dry.

– Distribution: Finally we must study rains distribution. Does it rain all months? Is there any dry season? how long does it last?

 You must remember that, commonly, every bar below temperature´s line must be took as a dry month or drought.
