Determining Turbulence Based on Richardson Numbers from the Historical Data of Radiosonde Kualanamu Meteorology Station using Machine Learning in 2015 - 2018

Introduction

Turbulence is a complex phenomenon that can occur on a small scale and short time, often detected when there is a change in wind direction and wind speed to height. This phenomenon has a significant impact on flight safety and passenger comfort, making it essential to predict turbulence accurately. In this context, Richardson's number plays a crucial role in predicting atmospheric stability and the potential for turbulence. This study aims to determine the symptoms of turbulence and develop a better forecasting method using the Machine Learning approach.

The Importance of Turbulence Prediction

Turbulence prediction is a critical aspect of aviation safety, as it can lead to severe consequences, including loss of life and damage to aircraft. The ability to predict turbulence accurately is essential to ensure the safety of passengers and crew members. In recent years, the aviation industry has faced numerous challenges related to turbulence, including the loss of several aircraft due to turbulence-related incidents. Therefore, the development of a reliable turbulence prediction method is crucial to mitigate these risks.

The Role of Richardson's Number

Richardson's number is a dimensionless quantity that plays a significant role in predicting atmospheric stability and the potential for turbulence. This number is calculated based on the ratio of the square of the wind speed to the product of the Coriolis parameter and the square of the height. The Richardson's number is used to determine the stability of the atmosphere, with values close to zero indicating unstable conditions and values close to one indicating stable conditions.

Methodology

This study used radiosonde data from the Kualanamu Meteorology Station between 2015 and 2018. The data included 1,440 observations at 00.00 UTC and 1,433 observations at 12.00 UTC. The method used in this study is the Support Vector Machine (SVM), one of the techniques in Machine Learning that has high capabilities in data classification. The SVM method was used to analyze the historical data and detect symptoms of turbulence.

Analysis of Results

The use of the Support Vector Machine method in this study provides very promising results. The forecasting results show that the percentage of errors (É›) is very close to 0, even in certain layers, the error value is equal to 0. This shows that SVM is able to provide high accuracy in predicting turbulence. This high accuracy shows the great potential of the Machine Learning method to be used in weather forecasts, especially in the identification and management of turbulence.

Conclusion

From the results of this study, it can be concluded that the Support Vector Machine method has a high ability to predict turbulence at the height of the flight, with the use of Richardson as the main parameter. The success in this study provides hope for further development in weather forecasting technology, so that it can help in improving flight safety. Thus, the integration between machine learning and meteorological techniques can produce innovative solutions in overcoming the challenges faced in the current aviation industry.

Future Directions

This study provides a foundation for further research in the field of turbulence prediction using Machine Learning. Future studies can focus on improving the accuracy of the SVM method by incorporating additional parameters, such as wind direction and temperature. Additionally, the study can be extended to include data from other meteorological stations to improve the generalizability of the results.
