The most common disturbance-generating weather systems that affect the Luquillo Mountains are (1) cyclonic systems, (2) noncyclonic intertropical systems, (3) extratropical frontal systems, and (4) large- scale, coupled ocean-atmospheric events (e.g., North Atlantic Oscillation, El Niño-Southern Oscillation). Unlike some tropical forests, the Luquillo Mountains do not commonly have disturbances associated with the passage of the Inter-Tropical Convergence Zone (ITCZ) or monsoonal rains.

The focal climatic questions being addressed by the Luquillo Critical Zone Observatory concern how atmospheric inputs (e.g. rainfall, cloud water inputs, nutrients, dust etc.) vary spatially and temporally across the Luquillo Mountains.  Research facilities include a series of weather stations, above canopy towers, and long-term records of climate and rainfall chemistry.
