Which of the following statements is/are correct? 1. The tropical cyclones of China Sea are called typhoons. 2. The tropical cyclones of the West Indies are called tornadoes. 3. The tropical cyclones of Australia are called willy- willies. 4. Formation of an anticyclone results in stormy weather condition. Select the correct answer using the code given below.

Tropical cyclones are regional weather phenomena known by various names. Statement 1 is correct as tropical cyclones in the China Sea and Western Pacific are termed typhoons [5]. Statement 2 is incorrect because tropical cyclones in the West Indies (Caribbean) are called hurricanes, whereas tornadoes are smaller-scale, violent rotating columns of air over land [3]. Statement 3 is correct as 'willy-willies' is the traditional regional name for tropical cyclones in Australia, particularly the north-western region [5]. Statement 4 is incorrect because anticyclones are high-pressure systems characterized by descending air, which typically results in clear, settled weather rather than stormy conditions [5]. In contrast, cyclones are low-pressure systems associated with violent winds and storms [1]. Therefore, only statements 1 and 3 are accurate.
