The correct answer is:
Warm water flows from B to A, causing the weather and climate in the region around B to be unusually warm in the summer.
Explanation:
1. Oceanic currents play a crucial role in determining the climate of coastal regions.
2. In this scenario, the oceanic current east of Brazil brings warm water from B to A.
3. This warm water flowing towards A influences the weather and climate in the region around B, making it unusually warm, especially in the summer.
4. Therefore, the movement of warm water from B to A has a direct impact on the temperature experienced in the respective regions.
Understanding the direction and temperature of oceanic currents helps in predicting and understanding the climatic conditions of coastal areas, like the effect seen in the region east of Brazil.
