Moreover, stratus clouds, which appear as flat, gray sheets covering the sky, are also prevalent in Alfenas. These clouds typically bring overcast conditions and may produce drizzle or light rain.

Seasonal Variations

The cloud patterns in Alfenas vary throughout the year due to seasonal changes. During the wet season (November to April), the region experiences increased cloud cover as a result of frequent rainfall. Cumulonimbus clouds, associated with thunderstorms, are common during this period. In contrast, the dry season (May to October) brings clearer skies with fewer clouds. Cirrus clouds, composed of ice crystals and appearing as thin, wispy streaks, are often visible during the dry season. These clouds are located at high altitudes and indicate fair weather.

Monthly Precipitation Distribution

During this time, Alfenas receives the majority of its annual precipitation, accounting for over 70%. The remaining months, from April to September, constitute the dry season, characterized by significantly lower rainfall.

Seasonal Variations

The seasonal variations in precipitation are primarily driven by the movement of the Intertropical Convergence Zone (ITCZ), a band of low pressure and high rainfall near the equator. During the wet season, the ITCZ shifts southward, bringing moist air and heavy rainfall to Alfenas. Conversely, during the dry season, the ITCZ moves northward, leaving behind drier conditions. The presence of the Serra da Mantiqueira mountain range, which lies to the southeast of Alfenas, also contributes to the city’s precipitation patterns. The mountains act as a barrier to moisture-carrying winds, resulting in lower rainfall on the eastern side of the range.
