Q. Sometimes hurricanes are accompanied by lightning too With help of a diagram, explain what changes in the climate lead to lightning during thunderstorms. PLEASE ANSWER ASAP...
Answers
Explanation:
three main ingredients for a thunderstorm to grow and develop are instability, moisture, and a lifting mechanism all explained in previous topics. The information below will further explain the development of thunderstorms when all of these ingredients are available.
The Cumulus stage of a growing thunderstorm
Figure A. The cumulus stage of a growing thunderstorm.
The life of a typical non-severe thunderstorm goes through three stages: Cumulus, Mature, and Dissipating. In the first stage (cumulus), we see the cloud that will become the thunderstorm starting to form and grow due to the rising thermal (or updraft). The rising updraft of air will begin to cool and condense as it rises, and in the case of thunderstorms, the thermal can travel tens of thousands of feet up before it finally stops! During this stage, small raindrops may begin to form and try to fall; however, the wind flow in the updraft can push the raindrops higher into the cloud rather than letting them fall out. At that level the raindrops collide and join into larger droplets due to the churning turbulence in the cloud.
Eventually, the raindrops will become large and heavy enough to fall from the cloud to the ground. This marks the beginning of the second stage (mature). The term downdraft is used to describe the rain and the cool air that begins to descend from the thunderstorm. You can think of a downdraft as a blob of cool air in the cloud that is heading toward the earth’s surface (opposite of an updraft). Downdrafts can change the temperature rapidly in an area in a short amount of time. For example, during a hot, summer afternoon in Sattley, California, the temperature was a blazing 97 degrees at 4:00 P.M. However, after a thunderstorm passed through the area, the downdraft dropped the temperature to a cool 57 degrees by 5:00 P.M., a 40 degree temperature swing in one hour! However, most storms cool things off a more modest 10-15 degrees because of evaporative cooling.
The mature stage of a thunderstorm
Figure B. The mature stage of a thunderstorm.
When the downdraft hits the ground, it begins to spread out in all directions. When this happens, a gust front can form. The gust front is basically a boundary that separates the rain-cooled air from the surrounding warm air shown in Figure C. Sometimes, a menacing-looking shelf cloud or roll cloud will form along the gust front. As you can imagine, the wind behind the gust front can be very strong, sometimes even reaching severe levels.

Lightning occurs during the process of hurricane because of the change in the pressure gradient.
Explanation:
- hurricanes are strong waves which floor at a very high velocity. This results in destruction and damage of life and property. actually the hurricanes take place when there is a huge pressure difference. Such pressure difference results in the flow of the clouds
- two or more clouds interact with each other and there is friction between the water vapours in the cloud resulting in lightning which takes place during hurricane.
