SAMRA 14 Flashcards by Raphaël Charlier

Rain falling but before get to ground…

Call it VIRGA, could have dry microburst.

-They can often be identified by the presence of “virga”
-They are linked with high-based cumulus and Altocumulus type clouds
-with this type of microburst, evaporative cooling intensifies the downdrafts

The main cooling machine condensation?

Adiabatic expansion

ILS full left to full right, how many degrees?

5°

Thunderstorm severe conditions, what to do?

Increase sever conditions away from the wave crest

50nm Squall line in advance of a cold front, you fly around this area, you will meet ?

SCT cumulus and CB, TCU parallel to the cold front

They have a "special TAF" weather, why?

Come faster

Jet stream change direction because?

Low pressure

LLJ find in low or high pressure

Low pressure

Descend air be compressed, why?

Because around air have higher pressure (more dense)

Warm front with snow ice pellets, what to expect?

FZRA

Radio ground wave

As frequency increases attenuation increases

Position A?

Jet stream cloud

IFR prefered route

IFR start or end with NAV AIDS

Clear sky night, light winds, dewpoint close of temperature, what can you expect?

Radiation fog can _______ visibility

Radiation fog will be ?

In calm wind will be more thick

Radiation fog difficult to detect because?

Radar energy attenuation

Blind person need?

An individual briefing, don't need emergency.

Cold air mass will?

Cold air front steeper and advance quickly

If they have FOG above the sea, but no FOG on the ground?

Warm moist air, off shore wind

GFA LLJ

Low pressure blocked by high pressure
