An air mass that originates in the pacific ocean west of brazil is most likely what

Warm and wet

Explanation:

Air masses are large portions of air that have relatively homogeneous internal temperature, pressure and humidity conditions, influenced by the region where they are formed. The place of formation of the air mass is called the region of origin, this is where the air mass will acquire its characteristics of temperature, pressure and humidity. Therefore, an air mass originating from western Brazil, will have common characteristics of a tropical region, that is, this air mass will be wet and have a high temperature.

For this reason, we can guarantee that an air mass that originates in the Pacific Ocean west of Brazil is likely to be warm and wet.
