"Measurement of Precipitation" Weather PPT Courseware 2

Steps to make a simple rain gauge

1. Find a straight transparent cup (or beverage bottle) with a height of more than 15 cm.

2. Use a ruler to draw a scale on the paper, in millimeters.

3. Stick the paper strip vertically to the outside of the cup so that the 0 mark on the paper strip is aligned with the bottom of the cup.

Does the diameter of the rain gauge affect the measurement?

Is it okay to use rain gauges of different sizes to measure precipitation?

Simulate measured precipitation

1. Use a water spray bottle to simulate precipitation for 1 minute.

2. Place the rain gauge on a horizontal table and read the scale.

3. Convert to 24 hours, calculate the rainfall, and check the rainfall level.

1. Fill in the blanks

1. Precipitation is a basic characteristic of weather and an important data in the weather calendar. There are many forms of precipitation, the common ones include rain, snow, hail, etc.

2. A rain gauge is a device that measures the amount of precipitation. The water collecting funnel of the gauge is used to collect rainwater. The height of the rainwater in the container is the amount of precipitation.

3. We can use a straight transparent cup to make a rain gauge, and a scale should be attached to the outside of the cup.

4. Meteorologists distinguish rain levels based on the amount of precipitation.

2. Judgment

1. A rain gauge is a device that measures the amount of precipitation. ( )

2. Depending on how fast it rains, the meteorological station has formulated a rainfall scale. ( )

3. Choice

1. Rainfall level is calculated based on the precipitation amount within ( ) hour.

A.6 B.12 C.24 D.48

2. It rained 90 millimeters all day and night yesterday. According to the precipitation level table, we know it was ().

A.Heavy rain B.Extremely heavy rain C.Heavy rain D.Moderate rain

3. The amount of precipitation in moderate rain cannot exceed ( ) millimeters.

A.50 B.60 C.70 D.25

4. Short answer

How to measure the level of precipitation?

Answer: In rainy weather, use a homemade rain gauge to measure the amount of precipitation within 24 hours, and compare it with the grade table to determine the level of rain.
