Analysis of Storm Track and Strength

Indian Ocean: A map showing the movement of tropical cyclones that form and move to the Indian Ocean region. The map presents both past tracks and forecast tracks, along with the intensity classification of the storms using color bands (e.g., Tropical Depression (TD), Tropical Storm (TS), and Cyclonic Storm Categories 1–5). This information is used for monitoring, surveillance, and issuing cyclone warnings. It is an essential dataset for the region, including Thailand, which may be directly affected by storms moving from the Bay of Bengal. Pacific Ocean: A map showing the movement of tropical cyclones that form and move to the western Pacific Ocean. The map displays both past tracks and forecast tracks, along with the storm intensity classifications indicated by color bands (e.g., Tropical Depression (TD), Tropical Storm (TS), and Typhoon Categories 1–5). This information is used for monitoring and tracking tropical cyclone situations that may move toward Thailand, especially during the months of August to October.
