Is this how a "Great Red Spot" could start?
Jet stream in our latitudes, not only part travelling east to west but
forming a circle http://virga.sfsu.edu/gif/jetstream_atl_h84_00.gif in a couple of days time. Jetstreams with Rosby wave shedding is a quasi-stable system but could a circlular path become self-sustaining? |

Apparently stable and centre position, over 5 days, taking a retrograde
track southerly about 10 degrees of latitude and westerly 30 degrees of longitude |

It is thought that land masses are what ultimately destabilises these systems on Earth and that lack of such on gas giants is why these features last so long there. |

http://virga.sfsu.edu/gif/jetstream_atl_h120_00.gif
for June 17th looks similar to http://virga.sfsu.edu/gif/11060800_j...am_atl_h24.gif of June 8th . I wonder if it can get locked-in to a circle for another week |

looks as though it will break by the 20th
http://virga.sfsu.edu/gif/jetstream_atl_h120_00.gif 12 day reign is something though |

Tropical storms in the southern oceans show up at northern latitudes in it. But the red spot is an upper, upper atmosphere phenomenon and nobody knows how many layers of critical points such as the tropopause there are there. It is assumed the gasses methane and similar make up the atmosphere if I remember correctly but water is a lot lighter than methane is it not? You wouldn't fill a balloon with either but the methane one wouldn't float and the steam would head for the hills if you tried. I don't know what interactions the organic gasses would have with vapour if any. And who can state with any authority that it is too cold to have vapour in the upper atmosphere? It might easily get thrown there either by some sort of volcanic activity or by the storms themselves. Or more likely arrive from elsewhere. |

In article 6193e963-0e32-401c-80a8-
, says... It is assumed the gasses methane and similar make up the atmosphere if I remember correctly but water is a lot lighter than methane is it not? Water H20 2+16=18 Methane CH4 12+4=16 Methane is a little lighter than water. The vast majority of the atmosphere is, apparently, hydrogen and helium. -- Alan LeHun |
