Meteorology

according to international standard atmosphere, temperature decreases approximately 2 degrees

per 1000ft

- false


steam is another word for water vapour

- false


as temperature decreases, relative temperature increases

- true


saturated air has a relative humidity of 100%

- true


at relative humidity of 100%, condensation occurs

- true


the changing of gas into liquid is condensation

- true


condensation can be caused from decrease in temperature

- true


liquid changing into a gas is evaporation

- true


condensation occurs at dew point temperature

- true


the height above which clouds form is the dewpoint

- false


clouds are caused by air being cooled to dewpoint

- true

air expanding causes adiabatic cooling

- true


raising air is cooled by an adiabatic process

- true


orographic lift is rising due to heating

- false


air passing over hills is conection

- false


converging air occurs in low pressure areas

- true


very high clouds are in a group named alto

- false


puffy rain clouds are called cirrocumulus

- false


these clouds are usually associated with rain, nimbus or nimbo

- true


these clouds are usually associated with fog, lenticular

- false


sudden wind changes are common with or near cumulonimbus cloud

- true


thunderstorms are associated with a large lapse rate

- true

temperature drops as a warm front passes
- false

large areas of drizzle are associated with a warm front
- true

warm air overtakes cold air in a cold front
- false

thunderstorms are usually with cold fronts
- true

if the two air mass temperatures are similar, fronts are more severe
- false

the joining of two fronts is called an occlusion
- true

lines joining places of equal pressure are isogonals
- false

a mercury capsule is in a aneroid barometer
- false

a continuous readout of pressure  is given by a barograph
- true

bad weather is caused by a ridge of low pressure
- false
good weather and poor visibility are normally with high pressure areas
- true

low pressure areas cause convergence
- true

poor weather is associated with low pressure areas
- true

bumpy flying weather is caused by unstable conditions
- true

upper winds are expressed relative to magnetic north
- false

wind that is changeable and gusty is veering
- false

valley winds are caused by cool air descending down alleys
- false

surface winds are given relative to true north
- false

sea breeze blows from the sea towards the land
- true

winds that blow down the cool sides of hills are katabatic
- true

the rate at which the air temperature changes with altitude is elr (environmental lapse rate)

- true


the rate at which the temperature of dry air changes if it rises is dalr (dry adiabatic lapse rate)

- true


a large lapse rate has a stable environment

- false


if your oat (outside air temperature) decreases by 5 degrees c for every 1000ft that you climb, you can expect a bumpy ride and possible thunderstorms

- true


in industrial areas, visibility tends to be worse on the downwind side

- true


its hard to see an airfield etc directly below you in oblique visibility

- false


radiation fog is caused by cloud radiating its heat

- false


advection fog is caused by the earth cooling the air above it at night

- false


cloud base is the height of the lowest layer of cloud above sea level

- false


down draughts tend to occur in the lee side of hills

- true
