The ocean current influence the temperature conditions of the area. Warm currents bring about warm temperature over land surface.
Effects of ocean currents
Ocean currents have great influence on the climate and economic activities of the coastal regions.
· Warm ocean currents raise the temperature of the costs along which they flow while cold ocean currents lower the temperature.
· Winds blowing over warm currents are moist and bring rainfall to the coastal regions. Winds blowing over cold currents are dry and cool and hence they hardly carry any moisture.
· In places where warm and cold ocean currents meet, dense fog is produced. It reduces visibility and can cause dangerous accident.
· Ocean currents influence navigation. Ships sailing along the current will sail faster and save time and fuel. Which currents help to melt icebergs, which are a potential danger to ships.
