* Rainforest: Rainforests experience tropical rainforest climates. These are characterized by:

* High temperatures year-round: Usually between 20°C and 30°C (68°F and 86°F).

* Very high humidity: Due to constant rainfall.

* Heavy rainfall: Often exceeding 2,000 mm (80 inches) per year, distributed throughout the year.

* Little variation in temperature: Day and night temperatures remain relatively consistent.

* Desert: Deserts have arid climates. They are defined by:

* Low precipitation: Usually less than 250 mm (10 inches) per year.

* High temperatures: During the day, temperatures can reach extremes, especially in hot deserts.

* Low humidity: Deserts are very dry environments.

* Large temperature fluctuations: Between day and night, and between seasons.

* Savanna: Savannas have tropical savanna climates. These are characterized by:

* Warm temperatures year-round: Similar to rainforests, but with a slightly larger temperature range.

* Seasonal rainfall: Typically experiencing a distinct wet season and a dry season.

* Moderate rainfall: Generally between 500 mm (20 inches) and 1,500 mm (60 inches) per year, concentrated in the wet season.

* Grasslands with scattered trees: The distinct wet and dry seasons influence vegetation patterns.

In summary:

* Rainforest: Tropical rainforest climate

* Desert: Arid climate

* Savanna: Tropical savanna climate
