World Meteorological Day was established in 1951 to commemorate the World Meteorological Organization creation on 23th March 1950. This organization announces a slogan for World Meteorological Day every year, and this day is celebrated in all member countries.
The World Meteorological Organisation (WMO), an organization of the United Nations, was created on 23th March 1950 to replace the International Meteorological Organization. It began operations in 1951 to coordinate member nation in the fields of meteorology, operational hydrology, and Earth sciences for the security of their population. The first World Meteorological Day was held on 23th March 1961.

At 1:45 pm on 1 December 1783, professor Jacques Charles and the Robert brothers (Les Frères Robert) launched a new, manned hydrogen balloon from the Jardin des Tuileries in Paris, amid vast crowds and excitement.
The balloon was held on ropes and led to its final launch place by four of the leading noblemen in France, the Marechal de Richelieu, Marshal de Biron, the Bailli de Suffren, and the Duke of Chaulnes. Jacques Charles was accompanied by Nicolas-Louis Robert as co-pilot of the 380-cubic-metre, hydrogen-filled balloon. The envelope was fitted with a hydrogen release valve, and was covered with a net from which the basket was suspended. Sand ballast was used to control altitude. They ascended to a height of about 1,800 feet (550 m) and landed at sunset in Nesles-la-Vallée after a flight of 125 minutes, covering 36 km. The chasers on horseback, who were led by the Duc de Chartres, held down the craft while both Charles and Robert alighted.
Charles then decided to ascend again, but alone this time because the balloon had lost some of its hydrogen. This time he ascended rapidly to an altitude of about 3,000 metres, where he saw the sun again. He began suffering from aching pain in his ears so he ‘valved’ to release gas, and descended to land gently about 3 km away at Tour du Lay. Unlike the Robert brothers, Charles never flew again, although a balloon using hydrogen for its lift came to be called a Charlière in his honour.
Charles and Robert carried a barometer and a thermometer to measure the pressure and the temperature of the air, making this not only the first manned hydrogen balloon flight, but also the first balloon flight to provide meteorological measurements of the atmosphere above the Earth’s surface.
It is reported that 400,000 spectators witnessed the launch, and that hundreds had paid one crown each to help finance the construction and receive access to a “special enclosure” for a “close-up view” of the take-off. Among the “special enclosure” crowd was Benjamin Franklin, the diplomatic representative of the United States of America. Also present was Joseph Montgolfier, whom Charles honoured by asking him to release the small, bright green, pilot balloon to assess the wind and weather conditions.
On 27 May 1931, Auguste Piccard and Paul Kipfer took off from Augsburg, Germany, and reached a record altitude of 15,781 m (51,775 ft). (FAI Record File Number 10634) During this flight, Piccard was able to gather substantial data on the upper atmosphere, as well as measure cosmic rays. On 18 August 1932, launched from Dübendorf, Switzerland, Piccard and Max Cosyns made a second record-breaking ascent to 16,201 m (53,153 ft). (FAI Record File Number 6590) He ultimately made a total of twenty-seven balloon flights, setting a final record of 23,000 m (75,459 ft).
Here is the inside of an aluminium hot-air balloon tank. This ‘cut away’ clearly shows how a hot-air balloon cylinder works…
From the top. You can see on this tank – the liquid valve which draws liquid fuel from the tube at base of the tank (silver handwheel valve) and the vapour valve (red wheel regulator valve) which could run the vapour pilot light on your burner if it had one, the pressure-relief-valve (PRV) is shown with the black plastic dust cap on it, the bleed valve used when filling the tank is the small screw valve and in the centre, the dial for the float gauge indicates the amount of liquid fuel in the tank.
Inside. You can see the kinked ‘dip tube’, the contents float gauge, the bleed valve tube at a high fixed level to indicate when to stop filling as your tank is full enough and the pressure relief valve.
Important notes – Not all tanks have a kinked dip tube and cylinders can have different valve configurations.
Congratulations to all the pilots and teams, europeans and worlds are dope thanks to you all. Thanks to the whole national team for the help and healthy rivalry. It makes us stronger and more focused.
Thanks to David Bareford and his team for a challenging and interesting championship. It wasn’t an easy job to do with such a weather forecast on an mediterranean island, but we had it all: slow winds, fast take off, fog, clouds, missed targets, mud, all sorts of flags and great effort from all the pilots.
Thanks to Ricardo Aracil and his fantastic team for this event that we won’t forget. And we definitely won’t forget the award ceremonies, both of MBT and Europeans.
