Note that the meridional circulation is much lower than the zonal circulation, which transports heat between the day and night sides of the planet. All winds on Venus are ultimately driven by convection. [3] Hot air rises in the equatorial zone, where solar heating is concentrated and flows to the poles.
Venus' oceans may have boiled away in a runaway greenhouse effect. A runaway greenhouse effect involving carbon dioxide and water vapor likely occurred on Venus. [22] In this scenario, early Venus may have had a global ocean if the outgoing thermal radiation was below the Simpson–Nakajima limit but above the moist greenhouse limit. [2]
The episode also examines the planet Venus to inspect the runaway greenhouse effect. [2] The episode's title alludes to H. G. Wells ' novel published in 1914, The World Set Free , where Wells predicts that humanity will develop destructive nuclear weapons , perpetuating a devastating global war and forcing the world to come to its senses to ...
The terraforming of Venus or the terraformation of Venus is the hypothetical process of engineering the global environment of the planet Venus in order to make it suitable for human habitation. [1] [2] [3] Adjustments to the existing environment of Venus to support human life would require at least three major changes to the planet's atmosphere ...
This is due to its very dense atmosphere which consists of about 97% carbon dioxide. [86] Although Venus is about 30% closer to the Sun, it absorbs (and is warmed by) less sunlight than Earth, because Venus reflects 77% of incident sunlight while Earth reflects around 30%. In the absence of a greenhouse effect, the surface of Venus would be ...
A Sudden Stratospheric Warming miles above the North Pole (a natural event) with a warmed Arctic due to climate change piggy backing on that pattern = unstable PV & wavy extreme jet stream, with ...
The initial observations of Venus' super rotation were Earth-based. Modern GCM models and observations are often enhanced by looking at past ancient climates. In a model where Venus is assumed to have an atmospheric mass similar to Earth, SS-AS circulation could have dominated over super-rotation in an ancient thinner atmosphere. [2]
Planetary equilibrium temperature differs from the global mean temperature and surface air temperature, which are measured observationally by satellites or surface-based instruments, and may be warmer than the equilibrium temperature due to the greenhouse effect.
