De Bilt is a municipality and town in the province of Utrecht, Netherlands. It had a population of 42,824 in 2019. De Bilt houses the headquarters of the Royal Netherlands Meteorological Institute (KNMI).
Felix Andries Vening Meinesz was a Dutch geophysicist and geodesist. He is known for his invention of a precise method for measuring gravity (gravimetry). Thanks to his invention, it became possible to measure gravity at sea, which led him to the discovery of gravity anomalies above the ocean floor. He later attributed these anomalies to continental drift. He was a Fellow of the Royal Society.
The Burns' Day Storm was an extremely violent windstorm that took place on 25–26 January 1990 over north-western Europe. It is one of the strongest European windstorms on record. This storm has received different names as there is no official list of such events in Europe. Starting on the birthday of Scottish poet Robert Burns, it caused widespread damage and hurricane-force winds over a wide area. The storm was responsible for 47 deaths, although figures have ranged from 89 to over 100 across Europe.
HIRLAM, the High Resolution Limited Area Model, is a Numerical Weather Prediction (NWP) forecast system developed by the international HIRLAM programme.
The Buys Ballot Medal is a prize given out by the Royal Netherlands Academy of Arts and Sciences. It was instituted in 1888 to honour the achievements of the Dutch meteorologist C.H.D. Buys Ballot. The prize is awarded approximately every ten years to an individual that has made significant contributions to meteorology.
The Royal Dutch Meteorological Institute is the Dutch national weather forecasting service, which has its headquarters in De Bilt, in the province of Utrecht, central Netherlands.
The Rotterdam Marathon, currently branded NN Rotterdam Marathon, is an annual marathon that has been held in Rotterdam, Netherlands since 1981. It has been held in April every year since the third edition in 1984 and attracts many top athletes. It has also been ranked as one of the top 10 marathons in the world by Runner's World magazine. The event is the most popular marathon in the Netherlands, followed by the marathons of Amsterdam and Eindhoven.

The Czech Hydrometeorological Institute (CHMI) is within the Environmental Ministry of the Czech Republic. The head office and centralized workplaces of the CHMI, including the data processing, telecommunication and technical services, are located at the Institute's own campus in Prague.
A royal is a small sail flown immediately above the topgallant on square rigged sailing ships. It was originally called the "topgallant royal" and was used in light and favorable winds.
Hendrik (Henk) Tennekes was the director of research at the Royal Dutch Meteorological Institute, and was a Professor of Aeronautical Engineering at Pennsylvania State University and Professor of Meteorology at the Vrije Universiteit Amsterdam. He is known for his work in the fields of turbulence and multi-modal forecasting. He authored the textbooks The Simple Science of Flight: From Insects to Jumbo Jets and A First Course in Turbulence with John L. Lumley. The book "A First Course in Turbulence", is a classic that logs more than 2,000 citations on Google Scholar.
The ozone monitoring instrument (OMI) is a nadir-viewing visual and ultraviolet spectrometer aboard the NASA Aura spacecraft. Aura flies in formation about 15 minutes behind Aqua, both of which orbit the earth in a polar Sun-synchronous pattern. Aura was launched on July 15, 2004, and OMI has collected data since August 9, 2004. OMI can distinguish between aerosol types, such as smoke, dust, and sulfates, and can measure cloud pressure and coverage, which provide data to derive tropospheric ozone. OMI follows in the heritage of TOMS, SBUV, GOME, SCIAMACHY, and GOMOS. OMI measurements cover a spectral region of 264–504 nm (nanometers) with a spectral resolution between 0.42 nm and 0.63 nm and a nominal ground footprint of 13 × 24 km2 at nadir. The Aura satellite orbits at an altitude of 705 km in a sun-synchronous polar orbit with an exact 16-day repeat cycle and wit h a local equator crossing time of 13. 45 on the ascending node. The orbital inclination is 98.1 degrees, providing latitudinal coverage from 82° N to 82° S. It is a wide-field-imaging spectrometer with a 114° across-track viewing angle range that provides a 2600 km wide swath, enabling measurements with a daily global coverage. OMI is continuing the TOMS record for total ozone and other atmospheric parameters related to ozone chemistry and climate.
Nicolaas Samuelszoon Kruik, also known as Klaas Kruik and Nicolaes Krukius, was a Dutch land surveyor, cartographer, astronomer and weatherman. He is commemorated by the Museum De Cruquius.
In the Dutch honours system, most orders are the responsibility of ministers of the Netherlands Government. The house orders, however, are awarded at the discretion of the Dutch monarch alone.
www.meteoalarm.org is the official website from Europe’s national weather services that will provide advice on exceptional weather. It is intended for anyone travelling through Europe. Pictograms and colour-coded maps of Europe show at a glance where the weather in the next 24 till 48 hours might be, or soon become, dangerous. The level of risk is colour-coded, based on likely damage, disruption and danger.

Cyclone Quimburga, also referred to as the Lower Saxony Storm was a deadly European windstorm that struck northern and central Europe between 12–14 November 1972. The storm has been described as one of the most devastating storm events during the 20th century.
The United Kingdom's Met Office, in collaboration with its Irish counterpart Met Éireann and, since 2019, its Dutch counterpart the Royal Netherlands Meteorological Institute (KNMI), decided to introduce a storm naming system following the St Jude's day storm on 27–28 October 2013 which caused 17 deaths in Europe and the 2013–14 Atlantic winter storms in Europe to give a single, authoritative naming system to prevent confusion with the media and public using different names for the same storms.
