gouttes de pluie

Raindrops

200

Very small amount of water drops that appear to float with the air currents while falling in an irregular path

Drizzle

300

Occurs when a cold winter period is about to finish because of an approaching warm front. 

freezing Rain

400

Flaques d'eau

standing water/puddles

500

The temperature at which the air is saturated with the  water vapor it contains and condensation begins

Dew Point

SNOW/ICE

une congère

snowbank/snowdrift

200

bourrasque de neige

snow flurries

300

plaques de verglas

icy patches

400

Generally transparent , globular, solid grains of ice which have formed from the freezing of raindrops or the freezing of largely melted snowflakes when falling through a below freezing layer of air near the earth's surface

Sleet

500

 A thin layer of ice on a solid surface, which forms from water vapor in an above-freezing atmosphere coming in contact with a solid surface whose temperature is below freezing,

Frost

Wind

100

Vent très fort

Severe gale

200

courant d'air descendant

a down draught/down draft

300

A wind blowing in the direction of travel of a vehicle or aircraft; a wind blowing from behind

Tail wind

400

 a change in wind speed and/or direction over a short distance. It can occur either horizontally or vertically and is most often associated with strong temperature inversions or density gradients , can occur at high or low altitude.

Wind shear

500

A forecast of specific atmospheric conditions in terms of wind and temperature at certain altitudes, typically measured in feet above mean sea level. The forecast is specifically used for aviation purposes.

Winds Aloft

Visibility

100

Is produced by solid particles in suspension in the atmosphere, visibility is the same for mist

Haze

200

Broullard se dissipe

Fog lifts/ Clears away

300

 are expressed in terms of visibility, distance from clouds, and ceiling meeting or exceeding the minimums specified by VFR.

Visual  meteorological conditions  

VMC

400

 A term used to describe the base of the lowest cloud layer in the sky and it's one piece of information that both pilots and meteorologists use when describing the current weather conditions and a vital tool for both fields

Ceiling

500

RVR

Runway Visual Range

Clouds

100

Nuages fragmentés

Broken cloud

200

a continuous or fragmented distribution of clouds all sharing the same cloud base.

What is a cloud layer?

300

une concentration , amoncellement de nuages

A build up

400

Dans les nuages par intermittence

To fly in and out of the cloud

500

 an air mass that contains up and down drafts in convective loops and that moves and reacts as a single entity, functioning as the smallest unit of a storm-producing system
