What is one positive effect of tropical cyclones on coastal ecosystems?

One positive effect of tropical cyclones on coastal ecosystems is the replenishment of nutrients in coastal waters. During a tropical cyclone, strong winds and heavy rains can lead to significant runoff from the land. This runoff often carries a variety of nutrients, such as nitrogen and phosphorus, into the coastal marine environment. As these nutrients are introduced into the water, they can stimulate primary productivity, promoting the growth of phytoplankton and supporting the broader food web.

The influx of nutrients can enhance the health and productivity of coastal ecosystems, including coral reefs and mangroves, which rely on nutrient-rich waters to sustain their diverse biological communities. This can lead to increased fish populations over time, benefiting both wildlife and local fisheries that depend on healthy ocean environments.
