Summary
[edit]
| Description |
English: Taken during the North American ice storm of 1998, this water vapor image loop from 7 pm EST on January 6th through 7am EST on January 9th clearly shows the deep layered moisture being transported from the Gulf of Mexico toward the Northeast. In addition, the swirling "darker" imagery from New Mexico/Texas and lifting into the Mid-Atlantic is the upper atmospheric storm that delivers the heaviest precipitation to the northeast during the night of January 7th through midday on January 9th.
It is overlaid the 500 mb isohypses airflow and the lighning strikes are blue and green.
Français : Prise durant une partie du Verglas massif de 1998, cette boucle montre le contenu en eau de l'atmosphère sur l'Est de l'Amérique du Nord, tel que vue depuis un satellite météorologique. L'humidité est en ton de gris, les plus clairs montrant le contenu le plus important et avec la plus grande épaisseur dans la masse d'air. La spirale noire qui se forme durant la boucle, qui va du 7 janvier à 19h (locale) jusqu'au 9 janvier, montre la position du puissant courant-jet. Ce dernier transporte la vapeur d'eau est altitude où elles forme nuages et précipitations. Cette boucle représente la portion de l'événement, qui s'est passée du 4 au 10 janvier 1998, avec les plus grandes accumulations de pluie et de verglas.
On a superposé en jaune les lignes d'égales hauteurs à la pression de 500 hPa (isohypses) ce qui montrent la circulation atmsophérique d'altitude. Les +/- en bleu et vert représentent les coups de foudre. |
