A gustfront is:

Formed by the cold air outflow from a thunderstorm

Another name for a cold front

Characterized by heavy lightning

Normally encountered directly below a thunderstorm

The QFF at an airfield in California located 69 metres below sea level is 1030 hPa. The air temperature is 10°C lower than a standard atmosphere. What is the QNH?

It is not possible to give a definitive answer

1030 hPa

Less than 1030 hPa

More than 1030 hPa

In the troposphere the decrease of pressure per 100 m increase in height:

Is smaller at higher levels than at lower levels

Is greater at higher levels than at lower levels

Remains constant at all levels

Is in the order of 27 hPa near MSL

How are well separated CB clouds described on the Significant Weather Chart?

EMBD CB

OCNL CB

ISOL CB

FREQ CB

Under what condition does pressure altitude have the same value as density altitude?

At standard temperature

At sea level when the temperature is 0°C

When the altimeter has no position error

When the altimeter setting is 1013.2 hPa

How would you characterise an air temperature of -55°C at the 200 hPa level over western Europe?

Within +/-5°C of ISA

Low

High

Very high

Which of the following conditions is most likely to lead to the formation of advection fog?

Moist cold air moving over a warm surface

Dry cold air moving over a warm surface

Dry warm air moving over a cold surface

Moist warm air moving over a cold surface

If a saturated air mass descends down a slope its temperature increases at:

A lower rate than in dry air, as evaporation absorbs heat

The same rate as if the air mass were dry

A lower rate than in dry air, as condensation gives out heat

A higher rate than in dry air, as it gives up latent evaporation heat

A trough of low pressure on a surface synoptic chart...

Is an area of convergence and widespread ascent

Leads to descending air masses

Is a narrow band of ascent

Is an area of divergence and widespread ascent

The DALR is greater than the SALR because...

Saturated vapour pressure increases with increasing temperature

None is correct

Of the release of latent heat of evaporation

The rate of cooling of saturated air is reduced by the release of latent heat of condensation
