1The measurement of surface temperature is made:
- AAt ground level.
- BAt approximately 10 metres above ground level.
- CAt approximately 4 feet above ground level.
- DAt approximately 4 metres above ground level
2Cloud cover will reduce diurnal variation of temperature because:
- AIncoming solar radiation is partially reflected back to space and outgoing terrestrial radiation is reflected back to earth.
- BIncoming solar radiation is re-radiated back to space and atmospheric heating by convection will stop at the level of the cloud layer
- CThe cloud stops the sun rays getting through to the earth and also reduces outgoing conduction.
- DIncoming solar radiation is partially reflected back to space and
outgoing terrestrial radiation is mostly re-radiated from the cloud
layer back to the surface.
3Most accurate temperatures above the ground level are obtained by:
- ATephigram
- BAircraft reports
- CTemperature probes.
- DRadio sonde.
4The diurnal variation of temperature is:
- AGreater over sea than overland
- BLess over desert areas than over temperate grassland.
- CReduced anywhere by the presence of cloud.
- DIncreased anywhere as wind speed increases.
5Over continents and oceans, the relative temperature conditions are:
- AWarmer in winter over land, colder in summer over sea
- BColder in winter over land, warmer in winter over sea.
- CCold in winter over land and sea
- DWarmer in summer over land and sea.
6The process of change of state from a liquid mass to a gas mass is:
- ACondensation in which latent heat is released.
- BEvaporation in which latent heat is released
- CCondensation in which latent heat is absorbed
- DEvaporation in which latent heat is absorbed by the mass
7Air is classified as dry or saturated according to its relative humidity. If the
relative humidity were 95% the air would be classified as- AConditionally saturated.
- BNot saturated.
- CSaturated
- DDry
8On a wet bulb thermometer in an unsaturated atmosphere there will be a
reduction of temperature below that of the dry bulb thermometer because:- AHeat is absorbed during the process of condensation.
- BHeat is released during the process of condensation.
- CHeat is absorbed by the thermometer during the process of evaporation
- DHeat is released from the thermometer during the process of
evaporation.
9Relative humidity is:
- AAir temperature over wet bulb temperature * 100.
- BAir temperature over dew point temperature * 100.
- CThe actual mixing ratio of water vapour in a sample of air over the maximum mixing ratio of water vapour that this sample can contain * 100
- DThe maximum amount of water vapour that a sample of air can contain over the actual amount of water vapour the sample does contain * 100.
10Absolute humidity is
- AThe number of water droplets in a given quantity of air
- BThe mass of water vapour that a volume of air holds
- CThe maximum amount of water vapour that a given quantity of air can hold.
- DThe maximum number of water droplets that a given quantity of air can hold.
11Wet bulb temperature would normally be lower than the dry bulb temperature
because- Acondensation causes a release of latent heat.
- Bevaporation causes cooling of the bulb.
- Clatent heat is absorbed by the bulb thermometer.
- Dof condensation on the muslin wick of the bulb
12The wet bulb temperature
- AIs measured using a hydromete
- BIs the minimum temperature to which a thermometer bulb can be
cooled by the evaporation of water - CMeasures the dew point of air
- DIs the minimum temperature reached by the surface of the earth as
measured by a thermometer placed 1.2 metres above the ground.
13Which one of the following statements relating to atmospheric humidity is
correct:- AIf the air temperature falls then the absolute humidity must increase
- BThe absolute humidity is the mass of water vapour contained in unit volume of air.
- CThe diurnal variation of dewpoint temperature is greatest when skies are clear at night
- DThe dewpoint temperature is the temperature indicated by the wet bulb thermometer.
14When condensation takes place, the higher temperature, the _____ the amount of
latent heat_____:- Alesser released
- Bgrater absorbed
- Cgreater released
- Dlesser absorbed
15When water vapour changes to ice:
- ALatent heat is absorbed.
- BSpecific heat is released
- CLatent heat is released.
- DSpecific heat is absorbed.
16Throughout the 24hrs of a day the Relative Humidity can be expected to:
- AIncrease during the day and decrease at night.
- BStay reasonably constant throughout the 24 hours.
- CReduce during the day and increase at night.
- DOnly change with a change of airmass.
17During a night with a clear sky, surface temperature will_____RH will_____
and dewpoint will_____:- AFall, rise rise
- BRise, rise, fall.
- CFall, rise, remain the same.
- DFall, fall, remain the same
18A change of state directly from a solid to a vapour or vice versa is:
- AInsolation
- BCondensation
- CEvaporation
- DSublimation
19The instrument used for measuring the humidity of air is a:
- AHydrometer
- BHygrometer
- CWet bulb thermometer
- DHygroscope
20The process of change of state from a gas to a liquid is:
- AEvaporation in which latent heat is absorbed.
- BEvaporation in which latent heat is released.
- CCondensation in which latent heat is absorbed.
- DCondensation in which latent heat is released.
