Defined as the degree of hotness or coldness of the air It varies: Throughout the day (eg. Cooler in the early morning and hot in the afternoon)
There is a difference between temperatures at the equator and poles It is hotter near the equator then the poles
The height of land (High mountain to lowland) As you go higher, it gets colder. As you get closer to the surface, it gets warmer. This is because air is warmest at the surface
Temperature can be measured in different ways. You use a THERMOMETER to measure temperature. First measurement: Maximum Temperature (high) and Minimum Temperature (low).
Mean Daily Temperature (Daily Max. Temperature + Daily Min.Temperature) ÷ 2 Daily Temperature Range Daily Max. Temperature – Daily Min. Temperature Mean Monthly Temperature Sum of mean daily temperature for the month ÷ Number days in month.
Mean ANNUAL temperature Sum of monthly temperatures in the year ÷ 12 Annual temperature range Max. mean monthly temperature – Min. monthly temperature
It is a wooden box with louvers (Openings)rculate for the air to circulate. The roof is made of double layers to protect the instrument from the direct rays of the sun It is painted white to reflect the heat from the sun The box stands on four legs about 1 meter above the ground.
Refers to the amount of rain an area receives over a period of time.
It is made up of 5 parts (an outer casing, a copper cylinder, a glass bottle, a funnel and a separate measuring cylinder)
Measured in millimeters (mm) or centimeters (cm) Rainwater collected after 24 hours is emptied and measured. This is called daily rainfall. Monthly Rainfall refers to rainfall in a month Annual Rainfall refers to rainfall in a year
Wind is the movement of air from one place to another. This is due to difference in air pressure caused by heat.
We use a Wind Vane to record the direction of the wind.
Tropical Climate It lies on between the equator and the tropic of cancer and capricorn. The sun’s rays are more intense at or near the equator Experience high temperatures ranging from 20ºC to 30ºC Receives same amount of energy all year round Has high annual rainfall ranging from 1000mm to 2000mm or more. Hot and wet climate Examples???
Temperate Climate Lie between Tropic of Cancer and Arctic Circle, and Tropic of Capricorn and Antarctic Circle Experience four seasons every year: Spring, Summer, Autumn and Winter Receive different amounts of sunlight in different periods of the year. Moderate temperatures and moderate rainfall throughout the year Examples???
Polar Climate Lies between Arctic Circle and North Pole, and Antarctic Circle and South Pole. Experience summer and winter From March to September: North Pole experience six months of sun. From October to February: South Pole experience six months of sun Very Dry because of lack of water vapour Examples???
Daily Activities Weather will determine whether we stay indoors or participate in outdoor activities.
Housing Humans like to live in places that are not too hot or cold.
Tourism Some climates provide different tourism experiences
Production of Electricity Use of wind energy
Food and Water Supplies Different crops thrive under different conditions
Loss of lives and property Extreme conditions can destroy lives and property
