Where does precipitation occur mainly in summer?

Only in summer, precipitation in the form of rain was recorded in subequatorial climatic zones.

In such zones, the air temperature is high throughout the year, but, despite this fact, it rains only in summer.

This is due to the presence of two air masses: equatorial and tropical. The first air mass brings very high temperatures and dominates in the summer. The second comes closer to December (winter period). Thus, the masses replace each other, so the dry season prevails in winter, and it rains in summer. Australia is a prime example.
