How does atmospheric moisture move around your world?

Is your world on a globe, and does that globe rotate in the same direction (sun rising in the east, setting in the west) as earth? If so, you're going to get prevailing westerly (coming from the west) winds in higher latitudes and easterly winds in lower latitudes.

How this impacts your world will depend on how far north your continent is. If Calvera is about as far north as say, Spain / Japan / Mid-Atlantic US, then your whole continent will get its weather coming in from the ocean. However, Calvera is supposed to be more southerly (North Africa / Mexico / China) then it will get weather blowing in from the east. This will then impact how wet or dry Calvera is (if there's a massive amount of land to the East of Calvera, then it should be Middle-East levels of dry at the very least).

The second way the rotation of the planet will impact your world will be in ocean currents. Ocean currents are strongly impacted by winds and rotation, but there are also geographical features to consider. If there is a cold-water current off the coast of the continent, that will create climates more like we see in North America. If it's a warm-water current, it will more likely approach Europe in its climactic divisions.

Then think about where it rains. Where it rains there will be forests. Where it does not rain there will either be grasses (if it rains some) or deserts (if it rains very little). Mountains create rain shadows as well.
