World Meteorological Day 2022
World Meteorological Day 2022
The World Meteorological Day is celebrated on 23 March every year to commemorates the coming into force of the Convention establishing the World Meteorological Organization. The World Meteorological Day showcases the essential contribution of National Meteorological and Hydrological Services to the safety and wellbeing of society and is celebrated with activities around the world.
The themes for the World Meteorological Day 2022 is “Early Warning and Early Action”
Weather, climate and water extremes are becoming more frequent and intense in many parts of the world as a result of climate change. More of us are exposed than ever before to multiple related hazards, which are themselves evolving as a result of population growth, urbanization and environmental degradation.
Being prepared and able to act in a timely manner, can save many lives and protect the livelihoods of communities, both now and in the years to come.
An effective early warning and early action mechanism needs a constellation of observations, namely:
- accurate local ground-based observations which describes the local weather conditions
- balloon soundings to get the vertical profile of atmosphere
- observations from aircraft which are equipped with meteorological instruments
- satellite observations from space
All these observations are used as input in weather forecasting models. If, for example, you do not have the local cloud-based observations, the quality of the forecast remains poor. Unfortunately, this situation is felt in some of the regions worldwide, for example in Africa, Caribbean and Pacific islands we have limited observation networks. This in turn, is having a negative impact on the accuracy of weather forecasts and this lack of observations is having a global impact on the quality of model output.
The Secretary-General of World Meteorological Organisation, Prof Petteri Taalas has in his video address on this occasion stated that we are already witnessing growing number of disasters and by having proper early warning services we can protect lives, property, infrastructures and the biosphere.
Furthermore, Mr. P. Taalas pointed out that the World Meteorological Organisation is contributing significantly in talks about climate change mitigation. While the reduction of the emissions of carbon dioxide and methane is essential, it is also very important to pay attention to climate adaptation. There is evidence that the concentration of Greenhouse Gases and global warming is linked to extreme weather. The unabating rising trend in the concentration of carbon dioxide in the atmosphere means that the trend in extreme weather will continue in the coming decades with an increasing number of weather and climate disasters.
One way to mitigate the impacts of weather disasters is to invest in more effective early warning services.
