Oceans, Climate and Weather: World Meteorological Day 2022

Today is World Meteorological Day! Every year on 23rd March meteorologists and weather enthusiasts commemorate the coming of the 1950 Convention that led to the establishment of the World Meteorological Organization (WMO).

The day also highlights the services of National Meteorological and Hydrological Services in their contribution to the safety and well-being of societies. But what exactly does Meteorology mean?

The word meteorology is derived from the Greek word meteoron from 340 BC by Aristotle. Way back then, meteorology referred to any phenomenon in the sky including shooting stars.

Nowadays, the world of meteorology includes the scientific study of the atmosphere with a major focus on the weather and climate.

Within meteorology, scientists, researchers and meteorologists all aim to understand the physical and chemical nature of the atmosphere and its complex interactions with the Earth.

Meteorologists collect and analyse atmosphere data to determine our short and long term weather trends and forecasts. We also use the data to see how the climate has changed from the past and how it could change in the future.

This year, the theme for World Meteorological Day is "Early Warning and Early Action". The focus will be on the vital importance of Hydrometeorological and Climate Information for Disaster Risk Reduction.

Being prepared and able to act at the right time, in the right place, can save many lives and protect the livelihoods of communities everywhere, both now and in the future.
