The line graph illustrates the numerous cyclones worldwide from 1975 to 2000, divided into three categories according to their severity mild, bad, and severe.
Overall, while the number of cyclones in mild and bad decreased slightly, the figure for severe increased significantly before ending at a high level than its starting point. The figure for mild was the highest during the period shown.
From 1975 to 1980, both categories named mild and bad followed a downward trend. The figure for mild dropped steadily from the peak of 95 to approximately 85. Similarly, the number of cyclones in bad recorded the most significant decrease, falling from 50 to 41. From that time onwards, the number of cyclones in mild fluctuated rapidly before ending at a lower level than initially, at approximately 80. Between 1980 and 1995, the figure for bad increased slightly from 45 to 50 and remained at this level until 2000, the bad of cyclones decreased slightly from 50 to 45.
Regarding the other , the figure for severe showed an upward trend from 20 to approximately 25 between 1975 and 1995. In 2000, the number of cyclones in severe witnessed a decline, falling from 25 to 21
