Factors that Affect the Weather

                                                       

Do you know that there are several factors that affect the weather? If you didn´t, read this text to help you learn. You might also wonder what instruments are used to measure the weather.

Weather involves all the conditions of the movement of the air. A factor that affects the weather is the location of the place and air pressure, because as it warms air expands. The amount of the water vapor in the air is called humidity. Sometimes the ocean changes the weather humidity. High humidity can make the air feel wet and sticky. During the day the Earth’s surface takes heat from the sun and becomes warm quickly. The ocean is not as warm as it is on land. During the day, cool ocean breezes move toward the land.

Some instruments used to measure the weather are the thermometer, rain gauge, anemometer and barometer. The thermometer measures temperature in degrees Celsius or degrees Fahrenheit. The rain gauge measures the amount of precipitation that has fallen in an area. The anemometer calculates the wind speed in kilometers an hour or miles. The barometer measures air pressure in units called milliards.

 An air mass is a large body of air that has about the same, temperature, air pressure and moisture throughout. They don’t stay in the place they form .As Earth moves the air masses move from west to south. As they move they bump into each other and this is called a front. A front is the name of a clash of warm and cold air masses and when that happens, it starts to rain.

The water cycle also affects the weather as it affects how much precipitation occurs and the level of humidity in the air.

So, the factors that affect weather: the water cycle, the fronts, severe weather, air pressure and air.
