How does the Intertropical Convergence Zone (ITCZ) affect aviation weather patterns across Kenya during the transition periods (typically October-December and March-May)?

1. It brings heavy convective activity, widespread thunderstorms, and low-level wind shear due to converging air masses.
2. It creates extremely stable, dry air masses resulting in prolonged radiation fog and clear skies.
3. It causes strong, persistent westerly gale-force winds and low-altitude jet streams across the Rift Valley.
4. It has negligible impact on weather due to Kenya's proximity to the equator.
