Analysis of Rainfall Levels and Many Rainy Days in BMKG Wil 1 (Medan City) in 2021 - 2023 using Copula Gaussian Modeling

Medan City: A Region Prone to Weather Extremes

Medan City, located on the island of Sumatra, is known for its diverse and often unpredictable weather patterns. The region's climate is characterized by significant changes in rainfall and temperature, making it a hotspot for extreme weather events. In the period 2021 to 2023, the analysis of rainfall levels and many rainy days in the BMKG Wil 1 region became a pressing concern, particularly in relation to its impact on natural disasters. The relationship between rainfall and the number of rainy days has a profound implication in identifying the potential for extreme weather events, such as floods and landslides, which require effective mitigation strategies.

The Importance of Rainfall Analysis and Rainy Days

Changes in abnormal rainfall patterns and high variability in the combined probability of these two variables can be an indicator of weather instability. With the global climate change, this relationship can also be affected, resulting in shifting rainfall patterns and rainy days. Therefore, a deep understanding of the interconnection between rainfall, rainy days, and extreme weather is crucial. This allows for effective mitigation planning, including early warning systems, water resource management, and adaptation to the impact of climate change.

The Role of Copula Gaussian Modeling in Rainfall Analysis

In this analysis, Copula Gaussian modeling is used to explore the relationship between rainfall and many rainy days. This method is effective in capturing multivariate relationships by considering the abnormal distribution, providing a more accurate picture of the pattern of interaction between the two variables. Through this approach, researchers can identify patterns and trends that may not be seen in conventional statistical analysis.

Impact of Climate Change on Rainfall Patterns

Climate change not only affects the frequency and intensity of rainfall, but can also extend the dry or wet period. With this increased variability, people need to be prepared to face the potential for disasters that might occur. Therefore, accurate information about rainfall and rain days is very valuable for stakeholders, both in planning infrastructure development and in agricultural activities and disaster management.

The Need for Collaboration in Addressing Climate Change

Through the analysis of rainfall and many rainy days in BMKG WIL 1 for the period 2021 to 2023, it can be concluded that the relationship between the two variables is a key factor in predicting and responding to the threat of extreme weather. By using copula gaussian modeling, we can gain a deeper insight about existing patterns and trends, so that this information can be used for better planning in overcoming the impact of climate change and natural disasters. Given the importance of this understanding, collaboration between the government, scientists, and the community is very necessary to achieve a sustainable and effective solution.

Methodology and Data Analysis

The data used in this analysis was obtained from the BMKG Wil 1 region, covering the period 2021 to 2023. The data includes rainfall levels and the number of rainy days for each month. The Copula Gaussian modeling was applied to explore the relationship between the two variables. The results of the analysis were then used to identify patterns and trends in the data.

Results and Discussion

The results of the analysis show a significant relationship between rainfall levels and the number of rainy days in the BMKG Wil 1 region. The Copula Gaussian modeling was able to capture the multivariate relationship between the two variables, providing a more accurate picture of the pattern of interaction between them. The results also show that the relationship between rainfall and rainy days is affected by climate change, resulting in shifting rainfall patterns and rainy days.

Conclusion and Recommendations

In conclusion, the analysis of rainfall levels and many rainy days in BMKG WIL 1 for the period 2021 to 2023 using Copula Gaussian modeling has provided valuable insights into the relationship between the two variables. The results of the analysis show a significant relationship between rainfall levels and the number of rainy days, which is affected by climate change. Therefore, it is recommended that the government, scientists, and the community collaborate to develop effective mitigation strategies to address the impact of climate change and natural disasters.

Future Research Directions

Future research directions include the application of Copula Gaussian modeling to other regions and the analysis of other climate variables, such as temperature and humidity. Additionally, the development of early warning systems and water resource management strategies based on the results of this analysis is also recommended.

Limitations and Challenges

The limitations of this study include the use of a limited dataset and the assumption of a normal distribution for the rainfall and rainy days data. Additionally, the challenges of implementing effective mitigation strategies in the face of climate change and natural disasters are also significant. Therefore, further research is needed to address these limitations and challenges.
