Clouds Associated With Rainfall

Cumulonimbus clouds are a type of cumulus cloud associated with thunder storms and heavy precipitation. They are also a variation of nimbus or precipitation bearing clouds. They are formed beneath 20,000 ft. and are relatively close to the ground. This is why they have so much moisture. Cumulonimbus clouds are also known as thunderheads due to their unique mushroom shape.
These clouds often produce lightning in their heart. This is caused by ionized droplets in the clouds rubbing against each other. The static charge built up creates lightning. Cumulonimbus clouds need warm and humid conditions to form. This gives them the moist warm updrafts needed to produce them. In some instances a Thunderhead with enough energy can develop into a super cel l which can produce strong winds, flash floods, and a lot of lightning. Some can even become tornadoes given the right conditions.
Despite the heavy rainfall these clouds produce, the precipitation normally just lasts for around 20 minutes. This is because the clouds require not only a lot of energy to form but also expend a lot of energy. However, there are exceptions to the rule. There are also dry thunderstorms which are cumulonimbus cloud whose precipitation does not touch the ground. This type is common in the Western United States where the land is more arid . It is often cited as a cause of wild fires.
An overlooked result of Cumulonimbus clouds are flash floods. This was proven recently in Atlanta, Georgia area of the United States. The state had gone through a two year drought and water supplies such as creeks and rivers were low. However the fall season brought with *it* the end of the drought and a lot of Thunderstorms. Even though Atlanta is not near any major waterways, the resulting flash floods were on a scale seen only with areas near major rivers with wide flood plains. This demonstrates how much precipitation that Cumulonimbus clouds can produce even in a short amount of time.
Cumulonimbus clouds are a perfect example of how difference in altitude can affect the formation of clouds. Cumulonimbus clouds form in the lower part of the troposphere, the layer of the atmosphere closest to the surface of the Earth. This region due to evaporation and the greenhouse effect produces a lot of the warm updrafts that make creation of cumulus and cumulonimbus clouds possible. The turbulence created by the friction between air and the surface of the Earth combined with stored heat from the sun helps to drive the majority of weather.

Persoalan Clouds Associated With Rainfall diatas akan Kakak Tondra bantu menjawab yang dapat kamu lihat jawabannya dan pembahasannya seperti di bawah ini.

Halo Siti A, kakak bantu jawab ya.
Jawaban untuk soal di atas adalah B. It is formed close to the ground.
Soal ini menanyakan penyebabkan awan cumulonimbus memiliki banyak uap air.
Pada paragraf pertama terdapat kalimat “They are formed beneath 20,000 ft. and are relatively close to the ground. This is why they have so much moisture”, yang artinya “Mereka terbentuk di bawah 20.000 kaki dan relatif dekat dengan tanah. Inilah sebabnya mengapa mereka memiliki begitu banyak kelembaban.”
Berdasarkan kalimat tersebut, dapat disimpulkan bahwa penyebabkan awan cumulonimbus memiliki banyak uap air adalah karena terbentuk dekat dengan tanah.
Jadi, jawaban yang tepat adalah B. It is formed close to the ground.
Semoga membantu ya.
