Climate is the average pattern of weather conditions that occur in a region, which are observed and recorded over a period of years. (You will learn more about climate in Unit 4.) A climatograph is a graph of climate data for a specific region and is generated from data usually obtained over 30 years from local weather observation stations. A climatograph includes average monthly temperature and an average of the total monthly precipitation for each 12:44 PM Page 17 month. Comparing climatographs can give you a greater understanding of the temperature and precipitation patterns in regions within a biome. You can also use climatographs to compare temperature and precipitation patterns in regions that are in different biomes, as shown in Figure 1.9 on the previous page and Figure 1.10 below. On a climatograph, the month of the year is shown on the horizontal axis. Average temperature is shown on the right vertical axis, and average precipitation is shown on the left vertical axis.

Osoyoos is home to Canada’s only desert. It is the uppermost part of the Great Basin Desert and is called the Pocket Desert.

Chapter 1 Biomes and ecosystems are divisions of the biosphere. • MHR 17 DATE: NAME: CHAPTER 1 Practise Reading Climatographs CLASS: BLM 1-8 Goal • Compare climatographs from three locations that are typical of different biomes. Question What inferences can you make by comparing the climatographs from three locations? What to Do The following climatographs give temperature and precipitation data for three typical locations within three biomes. Use the data from the climatographs to complete the table below. You will have to estimate values. Copyright © 2008, McGraw-Hill Ryerson Limited, a subsidiary of the McGraw-Hill Companies. All rights reserved.
