World Meteorological Day
The Sun, the Earth and the Weather
The Sun delivers the energy that powers all life on Earth. It drives the weather, ocean currents and hydrological cycle. It shapes our moods and daily activities. It is the inspiration for music, photography and art.
The Sun is a star, just like the ones we can see in the night sky, but much, much closer. Located nearly 150 million kilometres from Earth, it is the heart of our solar system and keeps our planet warm enough for living things to thrive. For over 4.5 billion years, this hot ball of glowing plasma has been the driving force behind weather and climate, and life on Earth.
