Final answer:
The highest annual values for latent heat of evaporation occur in the tropical regions due to their warm temperatures and higher levels of evaporation.
Step-by-step explanation:
The highest annual values for latent heat of evaporation (LE) occur in the tropical regions. The warm temperatures in these latitude belts favor evaporation, leading to higher levels of latent heat of evaporation. This is because tropical regions receive more sunlight and have higher temperatures, which result in increased evaporation.
