Weather buoy |
Weather buoys are instruments which collect weather and ocean data within the world's oceans. They measure parameters such as air temperature at the ocean surface, water temperature, wave height, dominant wave period, barometric pressure, wind speed (steady and gusting), and wind direction. The buoys transmit this data via cell, radio or satellite communications to meteorological centers for use in weather forecasting and climate study. Both moored buoys and drifting buoys (drifting in the open ocean currents) are used.
Weather buoys can be recognized by their yellow color and flashing yellow light at night.
