Why is Brazil hot and rainy?

Brazil is located near the equator and has a tropical climate. Because Latin America has the largest tropical virgin forest on earth, the Amazon River flows through it, bordering the south coast of the Atlantic Ocean in the east and the south coast of the Pacific Ocean in the west. The direct sunlight temperature is high, the evaporation is large, and the Atlantic airflow is pumped in, which is easy to form precipitation. So its characteristic is that the weather changes are often monotonous and full of regularity. In the early morning, the weather is clear and cool. Near noon, the cumulus clouds in the sky develop strongly and become thicker. At one or two o'clock in the afternoon, the sky is overcast, thunder rumbles, and the rain pours down, and the rain can last until dusk. It was a little cold after the rain, but it became sultry again after sunrise the next day. So day after day, year after year, people call this climate "equatorial climate".
