Which one of the following cities has greater annual range of temperature?

The annual range of temperature is primarily determined by latitude and continentality. Kuala Lumpur, located near the equator (3°N), has a minimal annual range of approximately 1°C due to consistent solar radiation [3]. New Delhi (28°N) and Shanghai (31°N) experience significant seasonal variations; Shanghai, representing a China-type climate, has a range of about 25°C. However, Ulaanbaatar (47°N) exhibits the greatest range due to its high latitude and extreme continentality, being far from maritime influences. In Ulaanbaatar, average temperatures fluctuate from -21.0°C in January to 17.3°C in July, resulting in an annual range of approximately 38.3°C. This extreme variation is characteristic of the subarctic and continental climates of Central Asia, where the absence of large water bodies allows for rapid heating in summer and intense cooling in winter.
