Responda
-
O adiabatic expansion.
-
O expulsion of long-wave radiation.
-
O conductive mixing.

Responda
-
O rises
-
O falls
-
O remains steady
-
O depends on humidity
Questão 4
Questão
316 The heat energy required to change state, but not temperature, is called:
Responda
-
O latent heat.
-
O transient heat.
-
O specific heat.
-

Questão 5
Questão
317 [Fig.16] When is advection fog most likely to form?
Responda
-
O When warm, moist air moves across a cold land surface and is cooled below its dewpoint temperature.
-
O When warm, moist air moves across a warm sea surface and is cooled to saturation.
-
O When dry, warm air moves across a cold sea causing evaporation and consequently condensation.
-
O None of those
Questão 6
Questão
318 When a wind changes direction from northly to north-westerly, it is said to have:
Responda
-
O backed in either hemisphere
-
O backed in the northern hemisphere and veered in the southern hemisphere.
-
O veered in either hemisphere.

Questão 7
Questão
319 You depart from aerodrome of Kastelorizo (LGKJ), (situated 474 feet above mean sea level (AMSL) with a QNH of 1011 hpa set on the altimeter subscale. The flight is conducted towards an area of low pressure and you fail to update the subscale setting (due to being non-radio). You anticipate a visual landing at the aero¬drome οf Kasteli(LGTL). What will the altimeter read when the aircraft lands at the destination aerodrome, which has an elevation of 1180 feet AMSL, if the QNH is 994 hpa?
Responda
-
O 1690
-
O 1750
-
O 950
-
O 1197
Questão 8
Questão
320 Density will be low when the:
Responda
-
O pressure is low and temperature is high.
-
O pressure is low and temperature is low.
-
O pressure is high and temperature is high.
-
O pressure is high and temperature is low
Questão 9
Questão
321 A cumulonimbus with an anvil, signifies that the thunderstorm is in the:
Responda
-
O decaying stage.
-
O cumulus stage.
-
O mature stage.
-
O none of those.
Questão 10
Questão
322 The force that causes a parcel of air to start moving from an area of high pressure to an area of low pressure is called the:
Responda
-
O pressure gradient force.
-
O Coriolis force.
-
O gradient force.
-
O centrifugal force
Questão 11
Questão
323 If maritime air is heated from below, as it moves from its source region, it is likely to become:
Responda
-
O unstable.
-
O conditionally unstable.
-
O stable.
-
O none of those.
Questão 12
Questão
324 The rate of decrease of temperature in rising saturated air is less than for rising unsaturated air. Why is this the case?
Responda
-
O Latent heat is released during the condensation process, and therefore warms the surrounding air, reducing the rate of temperature decrease.
-
O Saturated air rises more slowly, with a resultant decrease in the rate of cooling.
-
O Saturated air resists mixing with the cooler upper air.
-
O Saturated air is more dence

O reflected radiation from the Earth's surface.
-
O direct short-wave radiation from the Sun.
-
O the latent heat of the water vapor
