As far as pressure belts are concerned, you'll see the same types of equatorial bands as we see on Earth, Jupiter, and Saturn. Pressure belts form due to the spherical shape of the planet unevenly heating the atmosphere at different latitudes. This phenomenon is independent of the underlying geography (provided the geography isn't piercing the atmosphere).
Going one step down, Hadley cells form from the directions of the pressure belts. Like the pressure belts, they form based on the planetary geometry (spherical, tilt) and will be quite similar to Earths. Since Hadley cells extend across the height of the atmosphere, the underlying geography won't affect their behavior.
Take another step down, and you'll reach the pressure cells. These are much more complicated and difficult to predict because they cover a host of phenomena and are dependent on intrinsically sensitive meteorological factors.
Pressure cells form from cold and hot air masses in the upper atmosphere (and typically from polar regions for high pressure cells). High pressure masses pushes air out creating a large clearing of clouds over a massive area. The Coriolis effect then shifts this into a cyclone mass. That in turn can transform into any number of other cyclones depending on the cyclogenesis.
Cyclogenesisis predominately dependent on the scale of the meteorological phenomena. The smaller it is, the more likely it's dependent on geographical phenomena. As far as your pressure cells are concerned, the underlying geography will determine their geometry strongly if the cell is small enough (i.e. Mesoscale). If the cell is large enough (tropical), then underlying geography will affect much less so. The exact nature though, will depend on the geography,
the meteorological state of the air mass and its neighbors, and various other meteorological factors that are extremely sensitive to the meteorological conditions.
Take Tornados for instance. They are formed by Mesocyclones (cyclonic low pressure cells) formed within strong thunderstorms. When a low wind collides with a higher altitude wind travelling perpendicular to the low wind, the low wind 'shears' the higher wind and causes the air to spin. Then, when the spinning air mass further into the low pressure cell it's pulled upwards, creating an updraft near the ground. This forms the funnel cloud. Then, if rainfall increases in the storm, a strong downdraft drags the mesocyclone with it. When the mesocyclone reaches below the cloud base, it pulls in cool air from the updraft region previously mentioned. The subsequent combination of cool and warm air forms the rotating wall. When the updraft increases in strength, a low pressure area is created near the ground which pulls the mesocyclone further down. This manifests as the funnel of condensation commonly known as the Torndao.
Notice how many factors played into it? This is why tornadoes largely occur in large flat areas. These areas provide the space necessary for powerful wind shearing to occur. Furthermore, the area also needs low pressure cells to form commonly. As such, this doesn't occur in deserts (another flat area) because such low pressure systems don't typically form in deserts.
Other Geographical Effects
Similarly, Mountainous areas will block small cells and funnel the air mass and winds alongside the range (or around the mountains). Coastal areas can (and will) feed high pressure cells. Deserts produce hot air in the day, and cold air at night; next to a coast they will cause a daily shift in air masses back and forth, etc.
Largely the formation of cells is dependent first on atmospheric conditions, then geographical conditions.
Errata: I didn't cover tornadoes, storms, and other phenomenon because their formation is much more dependent on how a given storm moves and a host of other factors.
Ultimately, meteorological processes are chaotic processes, therefore they are absurdly sensitive to every condition and parameter that effects them. As a result, even with the knowledge of how the systems form, we cannot fully predict them. Case in point: predicting tornadoes, tropical storms, earthquakes, et cetera. You don't need to fully predict every aspect of your world. By all means use artistic license where necessary.
What you do know is how the geography can effect the local weather generally. Your Pressure Belts and Hadley cells should look similar to (if not identical) to Earth's. Your Pressure Cells on the other hand are impossible to forecast here. They will form and breakdown with storms and high/low pressure systems. The only statistically predictable phenomenon you have is the change in the local heat capacity of the equatorial strip with respect to the orbital tilt; but, that will only affect local weather phenomena, not the atmosphere miles above it. At the very least you'll have a North/South oscillatory shift in the pressure cells as the North/South coastlines are heated unevenly (tilt). Otherwise, the land area is likely too small to suggest other statistically
reliable weather phenomena.
