Answer 1

-1.1 Tropical cyclones generally move in a counterclockwise direction in the Southern Hemisphere.

-1.2 Evidence suggesting that this tropical cyclone is in the Southern Hemisphere can be seen in the path of the cyclone, which curves to the left.

-1.3 The dangerous quadrant/semicircle of a tropical cyclone is formed due to the combination of the storm's forward motion and the rotation of the cyclone. The strongest winds and heaviest rainfall are typically found in this quadrant.

-1.4 One possible reason for the re-curvature or change of direction of a tropical cyclone could be the influence of upper-level winds or the interaction with other weather systems.

-1.5 The dangerous quadrant/semicircle of a tropical cyclone is associated with severe weather conditions. This includes strong and gusty winds, heavy rainfall, storm surges, and the potential for tornadoes. Coastal areas in the path of the dangerous quadrant/semicircle can experience significant damage to structures, flooding, and the risk of coastal erosion. It is crucial for residents in these areas to take necessary precautions and follow any evacuation orders to ensure their safety
