Thermal parameters: BL top height / BL depth / BL topvariab / W* / B/S ratio / Convergence   /  Wind parameters  /  sfc parameters  /  clouds parameters





Quick help: Average dry thermal updraft strength near mid-BL height. Subtract glider descent rate to get average vario reading for cloudless thermals. Updraft strengths will be stronger than this forecast if convective clouds are present, since cloud condensation adds buoyancy aloft (i.e. "cloudsuck"). W* mainly depends (it is proportional) upon both the surface heating and the BL depth.
Aide rapide: Carte de la vitesse ascendante moyenne (W*) des thermiques mi-hauteur de la couche convective (CC) pour des thermques sans cumulus. Il faut soustraire le taux de chute en virage de votre planeur pour avoir la vitesse ascendante nette. W* dpend principalement de l'paisseur de la CC et du rchauffement au sol. Ce dernier dpend de la scheresse et du type de sol et de l'insolation. Plus la CC est paisse et plus W* est grand. 		sound15alpsfj101.png sound15alpsfj102.png sound15alpsfj103.png sound15alpsfj104.png sound15alpsfj105.png sound15alpsfj106.png sound15alpsfj107.png sound15alpsfj108.png sound15alpsfj109.png sound15alpsfj110.png sound15alpsfj111.png sound15alpsfj112.png sound15alpsfj113.png sound15alpsfj114.png sound15alpsfj115.png sound15alpsfj116.png sound15alpsfj117.png sound15alpsfj118.png sound15alpsfj119.png sound15alpsfj120.png sound15alpsfj121.png sound15alpsfj122.png sound15alpsfj123.png sound15alpsfj124.png sound15alpsfj125.png sound15alpsfj126.png sound15alpsfj127.png sound15alpsfj128.png sound15alpsfj129.png sound15alpsfj130.png sound15alpsfj131.png sound15alpsfj132.png sound15alpsfj133.png sound15alpsfj134.png sound15alpsfj135.png sound15alpsfj136.png sound15alpsfj137.png sound15alpsfj138.png sound15alpsfj139.png sound15alpsfj140.png sound15alpsfj141.png sound15alpsfj142.png sound15alpsfj143.png sound15alpsfj144.png sound15alpsfj145.png sound15alpsfj146.png sound15alpsfj147.png sound15alpsfj148.png sound15alpsfj149.png sound15alpsfj150.png sound15alpsfj151.png sound15alpsfj152.png sound15alpsfj153.png sound15alpsfj154.png sound15alpsfj155.png sound15alpsfj156.png sound15alpsfj157.png sound15alpsfj158.png sound15alpsfj159.png sound15alpsfj160.png sound15alpsfj161.png sound15alpsfj162.png sound15alpsfj163.png sound15alpsfj164.png sound15alpsfj165.png sound15alpsfj166.png sound15alpsfj167.png sound15alpsfj168.png sound15alpsfj169.png sound15alpsfj170.png sound15alpsfj171.png sound15alpsfj172.png sound15alpsfj173.png sound15alpsfj174.png sound15alpsfj175.png sound15alpsfj176.png sound15alpsfj177.png sound15alpsfj178.png sound15alpsfj179.png sound15alpsfj180.png sound15alpsfj181.png sound15alpsfj182.png sound15alpsfj183.png sound15alpsfj184.png sound15alpsfj185.png sound15alpsfj186.png sound15alpsfj187.png
