During which of the following stages of thunderstorm development is the downdraft?
The final third stage is the dissipating stage. Here, the downdraft is dominant. Eventually, the air beneath the storm gets too chilly for the updraft to continue rising, so the downdraft acts to “cut off” the updraft. At this point, the thunderstorm begins to fall apart.
What happens during the mature stage?
The thunderstorm enters the mature stage when the updraft continues to feed the storm, but precipitation begins to fall out of the storm, creating a downdraft (a column of air pushing downward). When the downdraft and rain-cooled air spreads out along the ground it forms a gust front, or a line of gusty winds.
What happens during the second stage or mature stage of a thunderstorm?
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.
What is the dissipating stage of thunderstorm?
The Dissipating Stage The downdraft cuts off the updraft. The storm no longer has a supply of warm moist air to maintain itself and therefore it dissipates. Light rain and weak outflow winds may remain for a while during this stage, before leaving behind just a remnant anvil top.
What are the stages in the development of a thunderstorm from first to last?
Most thunderstorms form in three stages: the developing stage, when storm clouds form; the mature stage, when the storm is fully formed; and the dissipating stage, when the storm weakens and breaks apart.
What are the three stages of thunderstorm development quizlet?
What are the three stages of thunderstorm development? cumulus stage, mature stage, dissipating stage.
What is cumulus stage?
The Towering Cumulus Stage A cumulus cloud begins to grow vertically, perhaps to a height of 20,000 feet (6 km ). Air within the cloud is dominated by updraft with some turbulent eddies around the edges. An example of towering cumulus.
What event signals the beginning of Stage 2?
What event signals the beginning of stage 2? When cloud droplets start to coalesce, they form larger and larger droplets, which eventually fall to the Earth as precipitation. This begins stage 2 of a thunderstorm.
What’s the first stage of thunderstorm?
Cumulus 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).
What are the steps of thunderstorm formation?
Most thunderstorms form in three stages: the developing stage, when storm clouds form; the mature stage, when the storm is fully formed; and the dissipating stage, when the storm weakens and breaks apart.
What are the three stages in the development of a thunderstorm discuss the key characteristics with each stage?
The life of a typical non-severe thunderstorm goes through three stages: Cumulus, Mature, and Dissipating.
What is the first stage of a thunderstorm?
cumulus stage 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).
Which event signals the beginning of the mature stage of a thunderstorm?
Which weather phenomenon signals the beginning of the mature stage of a thunderstorm? Precipitation beginning to fall.
What events signals the beginning of Stage 2?
What event signals the beginning of stage 2? When cloud droplets start to coalesce, they form larger and larger droplets, which eventually fall to the Earth as precipitation. This begins stage 2 of a thunderstorm.
What happens during Stage 3 of labor?
In the third stage of labor, the placenta is delivered. The placenta grows in your uterus and supplies your baby with food and oxygen through the umbilical cord. This stage is the shortest and usually doesn't take more than 20 minutes.
What is 2nd stage of labour?

In the third stage of labor, the placenta is delivered. The placenta grows in your uterus and supplies your baby with food and oxygen through the umbilical cord. This stage is the shortest and usually doesn't take more than 20 minutes.
What is third stage of labor?
The third stage of labor is the time from the delivery of the infant until delivery of the maternal placenta. The natural course of this final stage of childbirth involves cessation of umbilical cord pulsation, separation of the placenta from the uterine wall, and passage of the placenta through the birth canal.
What is the third stage of labor?
The third stage of labor is the time from the delivery of the infant until delivery of the maternal placenta. The natural course of this final stage of childbirth involves cessation of umbilical cord pulsation, separation of the placenta from the uterine wall, and passage of the placenta through the birth canal.
What is the 4th stage of labor?
The fourth stage of labor is the first hour or two after you deliver. During this time, your provider may have to repair an incision (episiotomy) or tears (lacerations) made during the delivery. This repair is made by giving you stitches with thread that absorbs on its own.
What happens during the 3rd stage of labor?
During the third stage of labor, you will deliver the placenta. How long it lasts: The placenta is typically delivered in 30 minutes, but the process can last as long as an hour.
