"Temperature and Air Temperature" Weather PPT Courseware 4

temperature

1. What is temperature?

Answer: How hot or cold the atmosphere is.

2. How to describe the temperature of a place?

Answer: Maximum temperature, minimum temperature, daily average temperature, monthly average temperature and annual average temperature.

When scientists measured the temperature, they placed three test tubes horizontally in a white shutter box with a north-facing door 1.5 meters above the ground.

what is the benefit?

The louver is 1.5 meters away from the ground to avoid the influence of ground temperature. Place it in an open place to ensure air circulation. The box is painted white to reduce solar radiation heat. The louver itself is also ventilated, in short, to measure the true air temperature as much as possible. Box paint color: Reduce solar radiation heat. Place it in a blind box: avoid direct sunlight and prevent wind and rain. Make the measured value closer to the accurate value.

The three thermometers measure changes in the maximum temperature, normal temperature, and minimum temperature respectively. Make temperatures more accurate

Use of thermometer

1. Hold the thermometer in the palm of your hand for 1-2 minutes.

2. Take a reading when the liquid column of the thermometer is stable.

3. When reading, the line of sight should be parallel to the liquid column of the thermometer.

Indoor and outdoor temperature record table

1. Measure the indoor temperature. Ask students to place the thermometer on the table (or hold it in front of them) for two minutes, read the temperature on the thermometer, and record it.

2. Measure the outdoor temperature. Each group chose a different outdoor location to measure the temperature. Record the measured air temperature and location.

1. Multiple choice questions

1. ( ) is an instrument for measuring temperature.

A. Thermometer B. Wind vane C. Rain gauge

2. The following operations, ( ) are the correct way to use the thermometer.

A. Glass bulb of hand-held thermometer

B. Place it in the measurement environment and take readings immediately.

C. When reading, keep your sight level with the liquid level of the thermometer.

3. In the record "27℃", it should read: ( ).

A. 27 ml B. 27 centimeters C. 27 seconds D. 27 degrees Celsius

4. 27℃ is read as ( )

A. Twenty-seven degrees Celsius B. Twenty-seven degrees C. Twenty-seven degrees Celsius

5. After learning about temperature measurement, we already know that the highest temperature of the day generally occurs in ( ).

A. Early morning B. Morning C. Around 2 pm D. Evening

6. The temperature measurement should be performed in ( ).

A． Indoor ventilation place B. A cool, ventilated place outdoors C. anywhere

7. Outdoor, the temperature in ( ) is generally higher than the temperature in ( ).

A. Sunny place B. Shade place

8. When observing and recording the temperature for a month, which of the following practices is wrong ( ).

A. Observe and record at the same time every day. B. During holidays, you can stop observing and recording.

C. Observe and record at the same place

2. Short answer

Think about it, what factors are related to the temperature height? What are the patterns of temperature changes?

Answer: The temperature is related to factors such as the season, weather conditions, and different times of the day.

The changing pattern of temperature is: the temperature is higher in summer and lower in winter; the temperature is higher on sunny days and lower on rainy days; the temperature is higher at noon and lower in the morning and evening.
