Très simple (ou presque) ! La première série de codes, ce sont =

des MÉTAR, c'est-à-dire des

rapports d'observation météorologique, et la seconde, un TAF, =

soit une prévision d'aérodrome.

Dans un MÉTAR ou dans un TAF, les éléments sont toujours =

identifés dans le même ordre, soit

le type de bulletin, l'indicatif de l'aérodrome ou de la station, =

la date et l'heure (d'observation dans

le cas du MÉTAR, d'émission et de validité dans le cas du TAF), =

le vent, la visibilité, le temps

significatif et les couches nuageuses. Dans le cas du MÉTAR, =

suivent la température, le point de

rosée, le calage altimétrique et les remarques. Dans le cas du =

TAF, on peut avoir une ou plusieurs

section supplémentaires (qui commencent par TEMPO, FMnnnn, BECMG ou =

PROBnn).

Il y a un site Web où on peut trouver deux tableaux de décodage. =

Un pour les TAF et l'autre pour

les MÉTAR. Je vais en indiquer l'adresse sitôt que je l'aurai =

retrouvé. En attendant, je vais traduire

le premier MÉTAR ci-haut :

METAR CYQB 141300Z 23008KT 8SM BKN040 13/09 A2963 RMK SC6 TCU ASOCTD =

SLP034

MÉTAR de CYQB (Aérodrome de Québec), observation de 141300Z (le =

14 du mois à 13 h 00

temps universel), le vent 23008KT (230 degrés vrais à 8 noeuds), =

la visibilité 8SM (8 milles

terrestres), BKN040 (couche nuageuse fragmentée (couvrant en 5/8 et =

7/8 du ciel) à 4000 pieds),

13/09 (température 13 degrés Celsius, point de rosée 9), A2963 =

(calage altimétrique à 29,63

pouces de mercure), RMK SC6 TCU ASOCTD SLP034 (en remarque, couche de =

6/8 d'étendue

de type stratocumulus, avec cumulus congestus associés, et pression =

au niveau moyen de la

mer de 1003,4 hectopascals). Voilà !

À la prochaine !
