What is Panasonic Global 4D Weather, a highly accurate global weather forecasting platform developed by Panasonic?

Various research resources have been cast for many years in predicting weather events that have a great impact on people and the environment, such as the arrival of cold waves and heat waves, the occurrence of drought and heavy rain, and the attack of typhoons. "Global (global) weather forecasting" technology predicting global weather change has been leaded by American and European forecasting systems, but it is said that Panasonic Prediction platform byPanasonic Global 4D Weather"Is in the stage of practical use.

In order to predict changes in the weather on a global scale, a very high performance supercomputer may be necessary, and the actual prediction was developed in the United StatesGFS(Global Forecast System) and European ECMWF (European Center for Medium-Range Weather Forecasts:European Mid-Term Forecast CenterThe state which is dominated by the two powers of Long Continues.

In many cases, GFS and ECMWF are compared with prediction accuracy, and it is generally said that ECMWF is more accurate than GFS. In addition to these two national-level prediction platforms, private weather forecasting companies and others may make their own forecasts, but the weather data to be referenced is basically brought about by the above two institutions It is a situation that it is not an exaggeration to say that it is actually a review of data.

It is the American corporation of Panasonic that has appeared in such a situation and is gradually increasing its presencePanasonic Weather SolutionsPanasonic Global 4D Weather "(PWS) is promoting R & D on a new platform. At the end of March 2016, PWS held a press conference to announce details of the platform of the company and announced the superiority of the system.

According to PWS, the company 's forecasting system has better predictive performance than the existing two platforms. Weather prediction accuracy can be measured by several measurement methods, one of which is to compare the value of "anomaly correlation". This is a numerical value showing the correlation between the predicted weather and the actual weather, but the larger the numerical value, the more accurate it is shown. Looking at this figure, it is clarified that GFS is 0.908, ECMWF is 0.923, and PWS's 4D Weather is 0.926, which realizes top accuracy exceeding ECMWF.

◆ Original observation system
For global scale weather modeling, it is necessary to perform a huge amount of calculation processing using a supercomputer, but we need meteorological observation data measured at the actual site in order to do this. For data measurement, we will start with data on various weather stations etc,RadiosondeWe are doing high-rise weather observation etc. using GFS and ECMFS as well as Panasonic Global 4D Weather in Panasonic Global 4D Weather, in addition to these information, accuracy using accuracy data acquired independently It is said that it made it possible to predict high.

It is "TAMDAR sensor" installed in the aircraft that makes it possible. This sensor is a sensor attached to the airframe side of the aircraft, measures and stores airflow, temperature, humidity, atmospheric pressure, etc. during flight and collects almost real time information by collecting data after landing Enable. This can be said to be a very big advantage when considering that conventional radiosondes stayed only twice a day observation.



This TAMDAR was a system that was mounted on an airplane under the initiative of the US government in the 1990's, initially it was a system to prevent ice adhesion to the aircraft. The TAMDAR sensor has been installed mainly by domestic flights installed by AirDat Inc., but Panasonic Avionics, a subsidiary of Panasonic, acquired AirDat in 2013 and is used for weather forecasting It is getting like it.

The size of the TAMDAR sensor is about this. It is said that it is attached to a small aircraft used mainly for domestic routes and acquires weather data.


It seems that it is sometimes mounted on UAV (unmanned aerial vehicle: drone) besides passenger aircraft.


The fact that its high accuracy appeared clearly was that it was a course prediction of the hurricane "Joaquin" that occurred in the Atlantic in 2015. Joaquin was predicted to land in the mainland of the United States, but in reality as indicated by the black line below, it did not land with grazing the Caribbean islands. In contrast, while American GFS predicted the mainland landfall, ECMWF and PWS 4D Weather had predicted that it would not land.


Currently, PWS provides meteorological data for enterprises and others, and concludes that specific company names can not be announced. It seems that the destination includes futures-related enterprises that are greatly affected by the weather, but it is said that it is not yet utilized in general weather forecasts.
