Which of the following is not a characteristic of the tropical desert climate?

The tropical desert climate is characterized by very low annual rainfall, resulting in arid conditions. The high temperatures and low humidity in this climate result in cloudless skies and frequent dust haze. The very high diurnal range of temperature (i.e. the difference between the day and night temperatures) is also a common feature of the tropical desert climate. However, a very low annual range of temperature is not a characteristic of this climate. In fact, temperatures in tropical deserts can vary widely throughout the year, with hot days and cool nights. Therefore, the correct option is: Very low annual range of temperature.
