Temperature- Meteorology- Oxford

#1. The measurement of surface temperature is made

at ground level

at approximately 10 metres from ground level

at approximately 4 feet above ground level

at approximately 4 metres above ground level

#2. The purpose of a “Stevenson screen” is to

maintain a moist atmosphere so that the wet bulb thermometer can function correctly

prevent the mercury freezing in the low winter temperatures

protect the thermometer from wind, weather and from direct sunshine

keep the wet and dry bulb thermometers away from surface extremes of temperature

#3. If temperature remains constant with an increase in altitude there is

an inversion

an inversion aloft

uniform lapse rate

an isothermal layer

#4. The surface of the earth is heated by

convection

conduction

long wave solar radiation

short wave solar radiation

#5. Cloud cover will reduce diurnal variation of temperature because

incoming solar radiation is reflected back to space and outgoing terrestrial radiation is reflected back to earth

incoming solar radiation is re-radiated back to space and atmospheric heating by convection will stop at the level of the cloud layer

the cloud stops the sun’s rays getting through to the earth and also reduces outgoing conduction

incoming solar radiation is reflected back to space and outgoing terrestrial radiation is re-radiated from the cloud layer back to the surface

#6. Diurnal variation of the surface temperature will

be unaffected by a change of wind speed

decrease as wind speed increases

increase as wind speed increases

be at a minimum in calm conditions

#7. Which of the following surfaces is likely to produce a higher than average diurnal variation of temperature

rock or concrete

water

snow

vegetation

#8. Most accurate temperatures above ground level are obtained by

tephigram

aircraft reports

temperature probe

radiosonde

#9. The method by which energy is transferred from one body to another by contact is called

radiation

convection

conduction

latent heat

#10. The diurnal variation of temperature is

greater over the sea than overland

less over desert areas than over temperate grassland

reduced anywhere by the presence of cloud

increased anywhere as wind speed increases

#11. The troposphere is heated largely by

absorption of the sun’s short wave radiation

radiation of heat from cloud tops and the earth’s surface

absorption by ozone of the sun’s short wave radiation

conduction from the surface, convection and the release of latent heat

#12. An inversion is one in which

there is no horizontal gradient of temperature

there is no change of temperature with height

there is an increase of temperature as height increases

there is a decrease of temperature as height increases

#13. The sun gives out amount of energy with wavelengths. The earth gives out relatively amounts of energy with relatively wavelengths

large, large, small, small

small, small, large, large

large, large, small, large

large, small, small, large

#14. With a clear night sky, the temperature change with height by early morning is most likely to show

a steady lapse rate averaging 2°C per 1000 ft

a stable lapse rate of 1°C per 1000 ft

an inversion above the surface with an isothermal layer above

an inversion from near the surface and a 2°C per 1000 ft lapse rate above

#15. Over continents and oceans, the relative temperature conditions are

warmer in winter over land, colder in summer over sea

colder in winter over land, warmer in winter over sea

cold in winter over land and sea

warmer in summer over land and sea
