1. This PowerPoint presentation will help you learn how to create a climograph and how to use climographs to compare climates in different places.

2. Weather is the state of the atmosphere at a given place and time
Weather is the state of the atmosphere at a given place and time. For example, right now, the temperature in Chicago, Illinois may be 56°F with rain.
Definitions taken from infoplease.com

3. Climate is the average condition of the atmosphere (such as temperature or precipitation) over a long period of time.
For example, the average temperature over the past 40 years for the month of February may be 32°F. The average precipitation is 2.8 inches.
Climate is the average of weather conditions in a place.

4. Just as the weather differs from day to day, the climate differs from place to place.

5. Just Checking What is weather? What is climate?
How are weather and climate different?
Weather is the state of the atmosphere at a given place and time.
Climate is the average condition of the atmosphere over a long period of time.
Weather is based on an observation at a particular time. Climate is based on many observations over many years.

6. Two important elements of weather and climate are: precipitation and temperature
Precipitation includes all forms of moisture falling to the surface of the earth. (Examples: rain, sleet, snow, hail)
Temperature is how warm or cool the air is outside.
* In this activity, mean temperature/precipitation is the same as average temperature/precipitation.
Mean=Average

7. In the following activity you will compare the climate in your area to the climate in Chongqing, China
First, we will learn how to develop a climograph by looking at an example for Orlando, Florida. A climograph is a graph that displays average (mean) precipitation and temperature for an area. A climograph is used to compare the climate in different places.
Next, we will create one climograph for Chongqing, China and another for your hometown.
Finally, you will use the two climographs you created to compare the climate in your hometown with the climate in Chongqing, China.

8. Practice making a climograph for Orlando, Florida
Find the climate data (average/mean temperature and precipitation) for Orlando, Florida.
Go to www. worldclimate.com
Type Orlando in the Search Box and click on the search button.
Click on the Orlando/Jetport/FL., United States of America link.
Scroll down to Orlando/Jetport/FL., United States of America

9. Noticing Precipitation Patterns
Click on the average rainfall link. Take note of any patterns you see:
* Note: This website uses the words “average rainfall” instead of “average precipitation”. It is more accurate to use “average precipitation” since this includes all forms of precipitation (such as rain, snow, and sleet).
Is there more precipitation in the summer months (July, August, September) or the winter months (January, February, March)?
What other patterns do you see in the average precipitation data for Orlando, Florida?

Summer months
Precipitation gradually increases from January to July and then gradually decreases from July to December.

10. To graph the average precipitation:
Label the x-axis (horizontal) with the months (Jan.-Dec.) and include a space for the yearly average precipitation.
Label the y-axis (vertical), on the left side of the graph, with the average precipitation levels in inches.
Next, plot the average precipitation for Jan. by drawing a bar over “Jan” reaching up to the amount of precipitation listed for that month. For our example, the Jan. average precipitation was 2.1 inches, so we drew a bar over Jan reaching the 2.1 level on the y-axis of the graph. Continue graphing the precipitation data in the same manner for each month and for the year.

11. Noticing Temperature Patterns

Summer
During the year temperatures gradually increase from January to July and August, then gradually decrease from July and August to December.

12. To graph the average temperature:
Use the same graph on which you plotted the average precipitation for Orlando, FL.
Label the y-axis (vertical), on the right side of the graph, with the average temperature levels in degrees Fahrenheit.
Next, plot the average temperature for Jan. by placing a dot over Jan at the average temperature listed for that month. For our example, the January average temperature was 59.9°F, so we placed a dot over Jan at the 59.9 level on the y-axis of the graph. Continue graphing the remaining temperature data in the same manner for each month and for the year.
Last, connect the dots by drawing a line from the dot for January and continue through the dot for December. Do not connect the dot for the year.

25. Something to think about
Would the average yearly temperature and the average yearly precipitation be a good way to describe the climate of an area?
Why or why not?
If you were to live in Chongqing, China for a year, what changes might you make in your clothing or activities because of the climate?
No. Because the average monthly temperatures and precipitation vary greatly from the average yearly temperature. Average daily temperatures and precipitation vary even more. Average yearly temperature and precipitation are a good way to compare different areas, but they do not provide a very detailed description of an area.
Answers will vary.

26. How Does the Climate Differ Across China?
There are 5 cities listed on the map above: Harbin, Beijing, Guangzhou, Fengdu and Kashi. In the next activity, you will create a series of climographs to compare the climates of these cities.
