Based on this chart, which city experiences the driest climate?
Answers
Climate graphs are used to illustrate the average temperature and rainfall experienced at a particular place over the course of a year. The graphs consist of a red line graph showing average monthly temperature, and a simple column graph showing average monthly rainfall figures. Rainfall is, by tradition, shown in blue. Some graphs show both the average daily high and low temperatures for each month. They do this by including two line graphs – the average monthly maximum temperature in red and the average monthly minimum in blue.
Governments around the world collect climate data. This makes it possible to compare the climate of different places. In Australia, the data is collected by the Bureau of Meteorology from more than 1,000 sites. While many sites have records going back more than 100 years, data is normally released to the public once the Bureau has records dating back 10 years.
Example: New York City
Key climate data for New York City in the United States of America are provided below in Figure 1. Daily recordings of temperature and precipitation (rainfall) have been processed to produce the average temperature and precipitation for each month. A yearly average for temperature has been calculated using the monthly averages. A total rainfall figure has been calculated by adding up all twelve months.
