Weather and Climate - CLAD

Climate refers to the average condition of the atmosphere (weather pattern) of a place over a

• day-to-day basis.

• long period of time of usually over 30 years.

• short period of time.

• lone period of time of about 10 years.

Diurnal temperature range =

• maximum daily temperature - minimum daily temperature

• sum of mean hourly temperatures / 24 hours

• maximum hourly temperature - minimum hourly temperature

• sum of mean monthly temperatures / 12 days

How does latitude influence temperatures?

• The lower the latitude, the lower the temperatures.

• It does not influence temperatures.

• The higher the latitude, the higher the temepratures.

• The lower the latitude, the higher the temperatures.

Places near the equator have higher temperatures because

• the solar energy travelled the shortest to reach the surface of places near the equator

• they receive the highest angle of incidence of sun rays (solar energy)

• the solar energy is most concentrated near the equator

• all of the above

Why are the peaks of mountains cooler than the ground surface?

• The longwave radiation from the sun gets reflected off the surface of the earth, and loses heat energy as it travels to higher altitudes. This results in lower temperatures.

• There are less air molecules thus lower pressure at higher altitudes. This means less solar energy is absorbed, leading to lower temperatures.

• There is less ground surface at higher altitudes, thus lesser solar energy absorbed, giving rise to lower temperatures.

• All of the above.

During summer land absorbs heat faster, and during winter land loses heat faster, than the sea.

• True

• False

Maritime effect refers to how the seas and oceans regulate the air temperatures of coastal areas.

• False

• True

During summer, the sea absorbs heat ..

• absorbs heat faster, thus the temperatures of coastal areas are generally hotter as compared to inland areas.

• absorbs heat slower, thus the temperatures of coastal areas are generally cooler as compared to inland areas.

• loses heat faster, thus the temperatures of coastal areas are generally cooler as compared to inland areas.

• loses heat slower, thus the temperatures of coastal areas are generally warmer as compared to inland areas.

Study the Figure. Warsaw in Poland would experience the...

• continental effect

• maritime effect

• global effect

• windy effect

The diurnal temperature range in places with little or no clouds is

• small because there is little temperature difference in the day and in the night

• large because of very high temperatures in the day, and very low temperatures at night

• small because the clouds help to reflect the heat in the day and in the night

• large because in the day most solar energy can reach the earth's surface, and in the night heat radiated from the earth surface can escape.
