"Changes and Differences in Temperature" PPT

"Changes and Differences in Temperature" PPT

Part One: Learning Objectives

1. Compare the "Temperature Change" chart, be able to simply describe the diurnal and annual changes in temperature, and master the method of calculating errors.

2. Be able to skillfully draw temperature curves based on monthly average temperature data

3. Understand the factors and distribution patterns that affect temperature distribution

Observed air temperature

The air temperature value is measured by a thermometer placed in a blind box.

The setting of the shutter: the door opens to the north, the inside and outside are painted with white paint, and the thermometer is 1.5 meters from the ground.

Determine air temperature

1. Observation of temperature is usually carried out 3 to 4 times a day, usually at ___ hour, ___ hour, ___ hour and ___ hour Beijing time.

2. Talk about the things to pay attention to when measuring temperature (read the activity on page 63 of the textbook):

3. Read the picture on the right: The temperature value at 2 o'clock is ____

The temperature value at 8 o'clock is____

The temperature value at 14:00 is___

The temperature value at 20 o'clock is___

4.The average daily temperature of the place_______

Changes and Differences in Temperature PPT, Part 2: Changes in Temperature

Thinking: How to calculate the average temperature?

Monthly average temperature = sum of daily average temperatures for 30 days in January divided by the number of days in the month

Annual average temperature = the average temperature for the twelve months of the year divided by 12.

Annual temperature range = highest monthly average temperature – lowest monthly average temperature

1. Diurnal changes in temperature: changes in temperature over a one-day period

2. Annual changes in temperature: temperature changes in a one-year cycle

3. Diurnal temperature range: the difference between the highest and lowest temperature in a day

4. Annual temperature range: the difference between the maximum monthly average temperature and the average monthly minimum temperature in a year

Temperature changes and differences PPT, part 3: How to make a temperature curve chart

(1) Draw the abscissa axis, divide it evenly into 12 segments, and label each month with the month.

(2) Draw the ordinate axis and mark the temperature scale according to equal temperature differences.

(3) Mark the temperature data for each month in the table with points, and then connect the points with smooth lines to draw a curve.

(4) Write the name of the picture in the appropriate position of the picture to complete the temperature curve diagram.

Step 1: Draw the horizontal axis, divide it into 12 equal segments, and label each month.

Step 2: Draw the ordinate axis and mark the temperature scale according to equal temperature differences.

Step 3: Mark the temperature data for each month in the table with points, then connect the points with smooth lines to draw a curve.

Step 4: Write the name of the picture in the appropriate position of the picture to complete the temperature curve chart

Changes and Differences in Temperature PPT, Part 5: Differences in Temperature

Think: What is an isotherm?

Find points on the map with the same temperature at the same time and connect them to form a line. The connected line is an isotherm.

A smooth curve connecting points on a map with equal temperatures.
