Study on Flying Patterns in Thunderstorm Situations

10.07.2019

Bad weather is one of the major reasons for delays in air traffic. Especially thunderstorm situations in summer challenge pilots and controllers. Thus weather information is used more and more in the cockpit and the control room. Facing thunderstorms, controllers find it very important to see doubtlessly at one glance no-go areas which aircraft should not enter.

To define such no go areas, a first study was already comissioned to MeteoSolutions GmbH by DFS Deutsche Flugsicherung GmbH (DFS). This study analysed the fly through patterns of commercial aircraft through adverse weather zones which were defined by thunderstorm warning levels. The warning leves came from the NowcastMix-Aviation product of Deutscher Wetterdienst (DWD), which is especially designed to support air traffic. One result of this study is shown in the chart below.

Data for this study were provided by DFS Deutsche Flugsicherung GmbH and Deutscher Wetterdienst (DWD). The project in the frame of SESAR 2020 PJ10 has received funding from the SESAR Joint Undertaking under the European Union’s Horizon 2020 research and innovation programme under grant agreement [734143].

Recently MeteoSolutions GmbH was assigned by DWD to apply the methodology which was worked out in the previous project on data of ground based weather radar systems (reflectivity data).

ValORTree: MeteoSolutions provides characteristic time series for future climate

26.04.2019

Meteosolutions GmbH was commissioned by the Technical University of Munich (TUM) to provide characteristic time series determined by measurement data and climate projections for phytotoxic climate chamber experiments and simultaneous modelling.

The Chair for Ecophysiology of Plants at the TUM is working on a research project funded by the German Environment Agency (UBA) entitled "Validation of phytotoxic ozone flux in needles and leaves as a requirement for a realistic, integrated risk assessment regarding the ecosystem services of forests in Germany" (ValORTree). The aim of this project is the estimation of the growth of beech and spruce trees under future climate conditions with focus on changing carbon dioxide (CO2) and ozone (O3) gas concentrations. The experimental realization takes place in newly equipped, walk-in climate chambers of the TUMmesa.

The provided characteristic time series were required for different meteorological variables that need to correspond meaningfully with each other. The dataset should be valid for the Spessart region in Germany and should reflect the typical annual cycle in hourly resolution. Characteristic time series are required for current and future time periods, with the use of different scenarios (RCP, representative concentration pathways) for generating future time periods.

For the implementation, measured data from the stations Spessart as well as ensemble data of regional climate simulations (ReKliEs-De and EURO-CORDEX) were used. Measurement data have been provided fully processed. Climate projection data were processed after the download to derive the climate signal. Based on the method for the determination of a test reference year (TRY) of the German National Meteorological Service (DWD, Deutscher Wetterdienst), the characteristic time series are determined. This method has been further developed for this purpose and was adapted to ground-level ozone concentration and its influencing factors. For the use of the determined characteristic time series, the data were customized to the climate chamber control system.

Based not only on the services provided in this project, MeteoSolutions GmbH has extended its services especially for the use of meteorological data from climate projections. Further information are available here.

Determination of characteristic time series of meteorological variables for phytotoxic climate chamber experiments

05.10.2018

Meteosolutions GmbH was commissioned by the Technical University of Munich (TUM) to determine and provide characteristic time series of meteorological variables for climate chamber experiments.

The Chair for Ecophysiology of Plants at the TUM is working on a research project funded by the German Environment Agency (UBA) entitled "Validation of phytotoxic ozone flux in needles and leaves as a requirement for a realistic, integrated risk assessment regarding the ecosystem services of forests in Germany" (ValORTree). The aim of this project is the estimation of the growth of beech and spruce trees under future climate conditions with focus on changing carbon dioxide (CO2) and ozone (O3) gas concentrations. For the experimental realization in the newly equipped, walk-in climate chambers of TUMmesa meteorological variables in hourly resolution are required, describing the long-term average of the weather conditions for one year. Those characteristic time series should be valid for the Spessart region in Germany, representing a low mountain range, and are required for a present and future period, with the use of different RCP scenarios for the time series generation of the future period.

For the implementation, data from measurement stations operated by the Hessian Agency for Nature Conservation, Environment and Geology (HLNUG) and the UBA as well as ensemble data from regional climate simulations (ReKliEs-De and EURO-CORDEX) are used and processed. Based on the method for the determination of a test reference year (TRY) of the Deutscher Wetterdienst (German National Meteorological Service), the characteristic time series are determined.

Presentation at the "2nd International Workshop on Meteorology and Air Traffic Management"

13.04.2018

The "2nd International Workshop on Meteorology and Air Traffic Management" will take place in Salzburg on 3rd and 4th of May 2018. There, the managing director of MeteoSolutions GmbH, Mr. Dipl.-Met. Jürgen Lang, will present the results of a study commissioned by DFS Deutsche Flugsicherung GmbH. The goal was to determine which convective weather events were flown through on the basis of meteorological data and the routes actually flown by commercial aircrafts.

The abstract of the presentation follows:

An Approach to Define Adverse Wx Zones Based on the Flight Management Performed by Pilots in Convective Weather Events

As a result of the prevailing weather conditions, such as lightning and hail, convective areas are a security risk to air traffic and must therefore be avoided by aircraft. The aim of an current project is to define convective areas (so-called ´Adverse Wx Zones´) geared towards civil aviation.

Using weather radar data, a radar reflectivity threshold of 37 dBZ has been frequently used in aviation as a criterion for dangerous convective weather events. This value was determined empirically in the 1980's based on a 6 class reflectivity product. This criterion is still often used in air traffic. So, it should be verified and if necessary redefined taking into account the current flight management performed by pilots during convective events.

For the study, radar raw data as well as convective warning levels from the NowCastMIX-Aviation system of the German National Weather Service (Deutscher Wetterdienst, DWD) were considered. In order to analyze the flight management performed by pilots in convective weather events, the data of flight trajectories were merged with the meteorological variables and statistically evaluated. The study area was limited to the lower airspace of the north of Germany controlled by the Area Control Center (ACC) of the German ATC agency (DFS Deutsche Flugsicherungs GmbH) in Bremen.

The study was carried out in two phases. First, the chosen approach was tested using a data set consisting of data from three selected days with thunderstorms in June 2017. In a subsequent phase, the investigation period was extended to June 2017. For this month, the periods of convective weather conditions were determined according to predefined criteria and the corresponding data for these periods were prepared and evaluated. Finally, the results were used for a first proposal to define ´Adverse Wx Zones´.

New DWD website made by MeteoSolutions GmbH

13.04.2018

In March, the German Weather Service (DWD) launched a website that is of particular interest to so-called probe chasers. This page shows the trajectories of the probes regularly launched at the aerological stations of the DWD to measure the vertical profiles of the atmosphere. The probe is carried by a balloon that bursts at very high altitudes. The probe then sinks again and signals the position for some time. The probe chasers are interested in finding the probes and sending them back to the DWD, for example. This way, probe chasers contribute to environmental protection.

The functionality of this website was developed by MeteoSolutions GmbH on behalf of DWD.

DIVMET is worth funding with regard to safety and comfort in air traffic

21.10.2016

DIVMET is a procedure developed by MeteoSolutions GmbH to determine safe, alternative flight routes in adverse weather conditions and particularly thunderstorms. It is primarily intended for use in the tactical phase, i.e. during the flight itself. Besides improving safety, it also helps to enhance comfort not only by avoiding turbulent flight phases but also by determining the arrival times at defined flyover points when an alternative flight path is followed.

BMWi Within the Meteorology for Air Traffic Management (MET4ATM) project financed within the BMWi’s LuFo V-2 aerospace research program, it is being investigated how this advantage can be used in the interaction with an arrival manager (AMAN) to optimise air traffic at an airport. MeteoSolutions GmbH is working closely with Selex ES GmbH (lead partner), Harris Orthogon GmbH and the Institute of Flight Guidance and Institute of Air Transportation Systems at the DLR on this project. The DIVMET procedure is also linked to a flight planning system developed by the German Aerospace Center (DLR). The project began in April of this year and will run until summer 2019. It is financed by the German Federal Ministry for Economic Affairs and Energy (Bundeministerium für Wirtschaft und Energie, BMWi).
