A hot tower is a tropical cumulonimbus cloud that reaches out of the lowest layer of the atmosphere, the troposphere, and into the stratosphere. These formations are called "hot" because of the large amount of latent heat released as water vapor condenses into liquid and freezes into ice within the cloud. Hot towers in regions of sufficient vorticity may acquire rotating updrafts; these are known as vortical hot towers In some instances, hot towers appear to develop characteristics of a supercell, with deep and persistent rotation present in the updraft. The role of hot towers in tropical weather was first formulated by Joanne Simpson in 1958. Hot towers dominated discussions in tropical meteorology in the 1960s and are now considered the main drivers of rising air within tropical cyclones

- 熱塔是一種熱帶積雨雲到達大氣，最下層出對流層，並進入同溫層。這些地層被稱為＂熱＂，因為當水蒸氣凝結成液體並在雲中凍結成冰時，會釋放出大量潛熱。渦度足夠大的熱塔可能會產生旋轉上升氣流；這些被稱為渦旋熱塔在某些情況下，熱塔似乎發展出「超級單體（英語：Supercell）」的特徵，在上升氣流中存在深度和持續的旋轉。熱塔在熱帶氣旋的作用於1958年由首次提出。熱塔在六十年代主導了熱帶氣象學的討論，現在被認為是熱帶氣旋中空氣上升的主要驅動因素，也是哈德里環流圈的主要組成部分。儘管七十年代科學文獻中熱塔的流行率有所下降，但熱塔仍然是一個活躍的研究領域。熱帶氣旋中熱塔的存在與熱帶氣旋增強情況有關。 (zh)

- Une tour convective (parfois appelée tour chaude) est un cumulonimbus des régions tropicales de grande extension verticale, le plus souvent associé à un cyclone tropical ou à la zone de convergence intertropicale, qui transperce la tropopause et atteint le bas de la stratosphère;dans les régions tropicales, la tropopause se situant à environ 15 km d'altitude. La présence de tours convectives laisse présager le renforcement d'un cyclone dans les 6 heures qui suivent. (fr)

The role of hot towers in tropical weather was first formulated by Joanne Simpson in 1958. Hot towers dominated discussions in tropical meteorology in the 1960s and are now considered the main drivers of rising air within tropical cyclones and a major component of the Hadley circulation. Although the prevalence of hot towers in scientific literature decreased in the 1970s, hot towers remain an active area of research. The presence of hot towers in tropical cyclones is correlated with an increase in the tropical cyclones's intensities. (en)
