Geography as level notes

Updated 22 Feb for the new syllabus 1. Differentiate between weather and climate. Weather is the condition of the atmosphere at a particular place and time whereas climate is the average condition of the atmosphere of a specific place over a long period of time, usually over 30 years.

Mean daily temperature — sum of hourly temperatures divided by 24 hours Diurnal temperature range —maximum temperature minus minimum temperature Mean monthly temperature — sum of mean daily temperatures in the month divided by number of days in the month Mean annual temperature — sum of mean monthly temperatures in the year divided by 1 Annual temperature range — maximum temperature minus minimum temperature recorded in a year Daily rainfall Geography as level notes the amount of rain that falls over 24 hours Monthly rainfall - total amount of rainwater collected throughout the month Annual rainfall - total amount of rainwater collected throughout the year.

Explain the daily and seasonal variations in temperature at a particular location. The temperature rises and falls as the Earth rotates from west to east. The location facing the sun experience day and the location which is away from the sun experience night.

Temperature rises during the day and falls at night.

Places along the equator have equal lengths of day and night all the year. Beyond the equator, places have longer days and hence higher temperatures in summer, and shorter days and lower temperatures in winter.

From June to August because of the position of the overhead sun, there is a higher intensity of the sun rays in the northern hemisphere. Thus the temperatures are higher during this period.

Compare and explain the variations in temperature between different locations. Places in low latitudes have higher temperatures because they receive vertical sunrays and hence more concentrated insolation. Temperatures are higher as the vertical sunrays travel through shorter distance of the atmosphere and smaller amount of insolation is lost through reflection and scattering.

Thus, the higher the altitude, the cooler the air temperature. With increasing altitude or elevation, air becomes less dense and contains less dust and water vapour. Heat from the earth's surface thus escapes more rapidly, thereby lowering the air temperature. In general, air temperature decreases with increasing altitude at a rate of about 0.

This change of temperature gradient is called the normal lapse rate or vertical lapse rate. Maritime effect - onshore winds blowing from the sea or ocean to coastal regions tend to lower summer temperatures and raise winter temperatures. Such moderating influence is called maritime influence and is confined to coastal areas.

The annual range of temperature in coastal regions is therefore smaller than that in inland regions. This is particularly felt in temperate regions.

Continental effect - Inland regions situated at a great distance from the sea have hotter summers and colder winters than coastal regions. Clouds reduce the amount of solar radiation that reaches the earth's surface and re-radiation that leaves the earth's surface.

At night thick clouds prevent rapid loss of long wave radiation heat energy from the earth's surface. On the other hand, night temperatures in these regions do not fall too much.Geography.
