1. The Sun and the weather. The energy that the Earth receives from the Sun is the basic cause of our changing weather. Solar heat warms the huge air masses that comprise large and small weather systems.
2.Climate is the long-term average of weather, typically averaged over a period of 30 years. More rigorously, it denotes the mean and variability of meteorological variables over a time spanning from months to millions of years
3.The polar climate regions are characterized by a lack of warm summers. Every month in a polar climate has an average temperature of less than 10 °C (50 °F). ... A polar climate consists of cool summers and very cold winters, which results in treeless tundra, glaciers, or a permanent or semi-permanent layer of ice.
4.. a thermometer that records the highest and lowest temperatures since it was last set
5.Calculate Mean Monthly Temperature
Calculate the mean monthly temperature by adding up the daily mean temperatures for each day of a month and then dividing that sum by the number of days in the month. For example, for the month of January, add up the 31 mean daily temperatures, then divide by 31.
6.The weather is a complex phenomenon as it can vary over very short periods of time. It can happen sometimes that it is sunny in the morning, but suddenly clouds appear from nowhere and it starts raining heavily. ... Since weather is such a complex phenomenon, it is not easy to predict.

1.Tropical climates are characterized by monthly average temperatures of 18 ℃ (64.4 ℉) or higher year-round and feature hot temperatures. ... There are normally only two seasons in tropical climates, a wet season and a dry season. The annual temperature range in tropical climates is normally very small. Sunlight is intense.
2.The polar bear
Their adaptations include: a white appearance - as camouflage from prey on the snow and ice. thick layers of fat and fur - for insulation against the cold. ... large feet - to distribute their load and increase grip on the ice.
4.Weather is a complex phenomenon. It can change considerably within days. In fact, on some days, the mornings are sunny, while it starts raining by afternoon. Thus, it is very difficult to predict weather.
