Páramo climates differ slightly depending on the specific location. In Colombia and northern Ecuador, air masses from the Intertropical Convergence Zone (ITCZ) have a substantial effect on the climate, and these regions tend to be consistently humid (approx. 70-85%) throughout the year. The Andes also play a key role in the climate of these regions as they cause an orographic uplift in which moist air rises. This creates continuous moisture via rain, clouds, and fog, with many of them receiving over of rain annually.
