It's a lot easier to argue that, at least in the models, 94L fully transitions and intensifies via convective, rather than baroclinic means

94L initially develops due to baroclinic influences in the right entrance of 90+ kt jet streak. Over the weekend, transitions tropically

Invest 94L looks to get baroclinic initial kick & then perhaps slowly transition to tropical storm in 4-days. HWRF 00z http://t.co/I707kHgu

baroclinic influences obviously evident with development of 94L in the Euro... it intensifies in the right entrance of a 90+ kt jet streak

@Brian2PointZero You mean "tropical" system. It's clearly baroclinic in origin. Though that hasn't stopped anyone before.

Imox baroclinic Instability on Hot Extrasolar Planets. (arXiv:1205.4453v1 [astro-ph.EP]) - http://arxiv.org/abs/1205.4453 Monday from physics updates on arXiv.org - Comment - Like We investigate baroclinic instability in flow conditions relevant to hot extrasolar planets. The instability is important for transporting and mixing heat, as well as for influencing large-scale variability on the planets. Both linear normal mode analysis and non-linear initial value calculations are carried out -- focusing on the freely-evolving, adiabatic situation. Using a high-resolution general circulation model (GCM) which solves the traditional primitive equations, we show that large-scale jets similar to those observed in current GCM simulations of hot extrasolar giant planets are likely to be baroclinically unstable on a timescale of few to few tens of planetary rotations, generating cyclones and anticyclones that drive weather systems. The growth rate and scale of the most unstable mode obtained in the linear analysis are in qualitative, good agreement with the full non-linear calculations. In general, unstable jets evolve differently depending on their signs (eastward or... - Imox
