  Observations of hot-Jupiter atmospheres show large variations in the location
of the hot spot and the amplitude of spectral features. Atmospheric flow
simulations using the commonly-employed forcing and initialization have
generally produced a large, monolithic patch of stationary hot area located
eastward of the substellar point at $\sim 3\!\times\! 10^{-3}$ MPa pressure
level. Here we perform high-resolution (up to T682) pseudospectral simulations
that accurately capture small-scale eddies and waves, inherent in hot-Jupiter
atmospheres due to ageostrophy. The atmospheres contain a large number of
intense storms over a wide range of scales, including the planetary-scale. The
latter sized storms dictate the large-scale spatial distribution and temporal
variability of hot, as well as cold, regions over the planet. In addition, the
large storms exhibit quasi-periodic life cycles within multiple equilibrium
states -- all identifiable in the disk-integrated time series of the
temperature flux.
