  Jupiter's atmosphere features a variety of clouds that are formed from the
interplay of chemistry and atmospheric dynamics, from the deep red color of the
Great Red Spot to the high altitude white ammonia clouds present in the zones
(bright bands in Jupiter's atmosphere). Beneath these upper level clouds, water
condensation occurs, and sporadically leads to the formation of towering
convective storms, driven by the release of large amounts of latent heat. These
storms result in a widespread disruption of the cloud and dynamical structure
of the atmosphere at the latitude where they form, making the study of these
events paramount in understanding the dynamics at depth, and the role of water
in the jovian atmosphere. In this work, we use the Explicit Planetary
hybrid-Isentropic Coordinate (EPIC) General Circulation Model (GCM) to study
the jovian atmosphere, with a focus on moist convective storm formation from
water condensation. We present the addition of a sub-grid scale moist
convective module to model convective water cloud formation. We focus on the
$24^\circ$ N latitude, the location of a high speed jetstream, where convective
upwellings have been observed every 4-5 years. We find that the potential of
convection, and vertical mass and energy flux of the atmosphere is strongly
correlated with the amount of water, and we determine an upper limit of the
amount of water in the the region surrounding the jet as twice the solar [O/H]
ratio.
