What weather phenomena can be expected at the edges of the ITCZ?

The Intertropical Convergence Zone (ITCZ) is known for its significant weather activity, particularly around its edges. When air masses converge at the ITCZ, it leads to rising air, which results in cooling and condensation, forming clouds and precipitation. This process often gives rise to severe weather phenomena, including thunderstorms.

At the edges of the ITCZ, the intense lifting of warm, moist air interacts with the surrounding drier air, which can create conditions ripe for severe thunderstorms. As the air pushes upward, it forms cumulonimbus clouds that can result in heavy rainfall, lightning, and strong winds. Thus, the expectation of severe thunderstorms at the edges of the ITCZ aligns perfectly with the meteorological characteristics associated with this region.

In contrast, the other options do not accurately represent the conditions at the ITCZ's boundaries. Stable weather conditions would not be associated with the active convergence of air masses, consistent high pressure does not prevail in regions of converging winds, and dry air masses typically characterize areas away from the ITCZ where descending air creates arid conditions rather than stormy weather.
