Low-level wind shear and airport safety

Low-level wind shear and airport safety
During this webinar, we will discuss the meteorological phenomena that cause low-level wind shear and briefly review International Civil Aviation Organization (ICAO) requirements and recommendations related to low- level wind shear.

​​​Air traffic controllers and pilots usually have no means of detecting low-level wind shear with the standard instrumentation available for them. It may even take the most experienced pilots by surprise and put them in a situation where the wrong decisions can have disastrous effects. Although the meteorological phenomenon known as wind shear has been recognized in aviation since the late 1960s, it is still not fully understood today. 

During this webinar, we will discuss the meteorological phenomena that cause low-level wind shear and briefly review International Civil Aviation Organization (ICAO) requirements and recommendations related to low- level wind shear.

A Low-Level Wind Shear Alert System (LLWAS) provides useful information on wind shear. Access to this kind of information eases the air traffic controller’s burden, increases the pilot’s confidence at a particular airport, and improves the overall safety of aircraft operations at an aerodrome.

Sc. in meteorology from University of Helsinki, Finland and works as an independent consultant in aeronautical meteorology. He has over 20 years of experience working for the International Civil Aviation Organization (ICAO), 1990-2011. During the last nine years, he was the Chief of Meteorology Section of the ICAO Air Navigation Bureau.

Juhani Polvinen has a Master’s Degree in Meteorology from the University of Helsinki.  Before joining Vaisala, he worked as a weather radar specialist at the Finnish Meteorological Institute. With over 17 years of experience at Vaisala, Juhani has become an expert in aviation meteorology focusing on low level windshear and its effects on airport operations. He has worked in close co-operation with the National Center for Atmospheric Research (NCAR) when developing low level windshear solutions for Vaisala. Juhani has been working closely with airport operators around the world and is an expert on airport operations, especially related to the challenges caused by adverse weather.
