World Meteorological Day takes place every year on 23 March and commemorates the coming into force on 23 March 1950 of the Convention establishing the World Meteorological Organization. It showcases the essential contribution of National Meteorological and Hydrological Services (NMHSs) to the safety and wellbeing of society and is celebrated with activities around the world. The themes chosen for World Meteorological Day reflect topical weather, climate or water-related issues.


Our theme for 2019 is The Sun, the Earth and the Weather and reflects the core purpose of WMO and the essential role of NMHSs in monitoring the Earth System in order to deliver daily weather forecasts and advise policy makers about climate variability and change. In doing so, the WMO community supports actions that protect lives and property from extreme weather and builds long-term climate resilience.

The Sun delivers the energy that powers all life on Earth. It drives the weather, ocean currents and the hydrological cycle. It shapes our mood and our daily activities. It is the inspiration for music, photography and art.

“The Sun can provide an alternative source of energy, which can be harnessed even in cloudy weather. Solar energy is indeed used worldwide and is increasingly popular for generating electricity or heating and desalinating water. Understanding how the Sun influence weather and climate phenomena is therefore critical to the core mission of WMO of building resilient societies.” – said In his message on the World Metrological Day Secretary-General of the World Meteorological Organization, Petteri Taalas.

Despite receiving just 30 days of sun per year, Belarus has followed the example of its European colleagues. Now, solar energy is the trend in Belarus. In the last few years, the country increased its solar energy production by 70 times, from 0.4m MW per hour in 2013 to 28m MW per hour in 2016, not including solar power stations belonging to businesses. This energy is enough to supply a small Belarusian town with energy for a year.

The European Union supports Belarus in its transition to solar energy. In the framework of the EU4Energy initiative, several EU-supported projects are taking place to help schools, kindergartens and hospitals convert to renewable energy sources.


The EU4Energy initiative aims to improve energy supply and promote energy efficiency and the use of renewables in the Eastern Partner countries, including Belarus. This way energy becomes cheaper and more affordable for citizens, state-run establishments and businesses. 

Solar energy is also supported at the state level. Thus, in 2010 Belarus adopted the law "On renewable energy sources", according to which" Belenergo " is guaranteed to buy solar electricity from the owners of solar installations connected to power grids.

Already this year, the Belarusian construction company CJSC “Belzarubezhstroy” will build the largest photoelectric station in our country with a capacity of 109 MW in the Cherikov district of the Mogilev region.

The construction of the station is aimed at the development of environmentally friendly solar energy in our country, the diversification of energy sources, reducing operating and transportation costs in connection with the provision of electricity to neighboring settlements.
