LESSON CONTENT

OUR WEATHER

Weather is the state of a particular environment at a given period of time.

Climate is the weather condition of a place over a long period of time.

A person that studies the weather and predict the weather is called a Meteorologist or weather forecaster.

The condition of the weather affect the way we behave and react.

There are different factors that affect weather, these are:

1. Wind
2. Sunshine
3. Rainfall
4. Temperature
5. Humidity
6. Cloud
7. Atmospheric pressure

Weather instrument and functions

The following are weather instruments:

1. Thermometer – it is used to measure the temperature of a person.
2. Barometer – it is used to measure the pressure of the atmosphere.
3. Anemometer – it is used to measure the speed of the wind.
4. Rain gauge – it is used to measure the quantity or amount of rainfall.
5. Hygrometer – it is used to measure water vapor in the air (relative humidity).
6. Clock – it is used to show time.
7. Photometer – used to measure Light intensity.

Weather Symbols

Meteorologist make use of these symbols when recording and forecasting weather.

The following are some of the symbols used to observe the condition of weather.

1. Sunny
2. Rainy
3. Cold
4. Cloudy
5. Lightning
6. Hot

GLOBAL WARMING

Global warming is an increase in the average temperature of the earth’s atmosphere that leads to the change of climate. This is caused by the release of harmful gases like carbon dioxide (co2), chlorofluorocarbons (CFCs) into the atmosphere.

The effect of global warming

1. Rising sea level
2. Increase in temperature
3. Excessive flood.
