• 😀 The climate in Zona da Mata is tropical and humid, with high temperatures and concentrated rainfall during the winter months.
• 😀 The Sertão is a semi-arid region, the driest in Brazil, with irregular and scarce rainfall and long periods of drought.
• 😀 In the Sertão, temporary rivers only flow during the rainy season, and the native vegetation is caatinga, adapted to dry conditions.
• 😀 The Agreste serves as a transition zone between the wet coastal Zona da Mata and the dry Sertão, with a mix of dry and more lush vegetation.
• 😀 The Meio Norte is situated between the Sertão and the Amazon rainforest, with increasing rainfall from east to west.
• 😀 The natural vegetation in Meio Norte includes the Mata de Cocais, featuring palms like Carnaúba and Babaçu, which are significant to the region's ecosystem.
