On August 26, the typhoon's convection slightly weakened, and the more intense convective activity became limited to the southern and eastern sides of the system.
22.
During the evening of October 19, the center of Rick became devoid of convective activity, resulting in the NHC downgrading it to a tropical storm.
23.
The system completed a cyclonic loop in the central gulf, As a result of wind shear, the center of circulation was separated from the deep convective activity.
24.
The geography of mountain ranges bordering the Mediterranean are conducive for severe weather and thunderstorms, with the sloped nature of mountainous regions permitting the development of convective activity.
25.
The ITCZ is formed by vertical motion largely appearing as convective activity of thunderstorms driven by solar heating, which effectively draw air in; these are the trade winds.
26.
It is often claimed that Flight 599 went down in or shortly after a thunderstorm, but meteorological records show that there was no significant convective activity at the time.
27.
Hours later, however, it began to weaken, The cloud pattern associated with the hurricane deteriorated on October 2, and the center of circulation was separated from the convective activity.
28.
Operationally, however, these winds were considered to be related to local convective activity rather than the storm itself and it was not considered to be a tropical storm until post-storm analysis.
29.
Upon being classified, the depression exhibited deep convective activity, with the tropical storm-force winds; however, the winds were determined to have been affected by rain and therefore not representative of the depression's actual intensity.
30.
The increased moisture results in more convective activity in the atmosphere _ the kind of rapid storm development that often produces several inches of rain, or a foot of snow, in a matter of hours.
