Analysis Of Cape Index And Total Index Thresholds Towards Cumulonimbus Cloud And Thunderstorm Events At Minangkabau International Airport

2026-05-12T03:27:46+00:00

Indonesia located along the equator and dominated by oceanic areas, is highly vulnerable to atmospheric dynamics and extreme convective weather. Minangkabau International Airport (BIM), situated in a coastal region of West Sumatra, is frequently affected by cumulonimbus (Cb) clouds and thunderstorms (TS), which pose risks to aviation safety. This study aims to determine the threshold values of the Convective Available Potential Energy (CAPE) index and the Total Totals Index (TT) that are appropriate for local conditions, based on radiosonde and synoptic observation data from 2019–2023, and verified using 2024 data. The CAPE and TT values were analyzed using Sturges’ method to determine frequency intervals and dichotomous analysis to establish threshold effectiveness. Results indicate that CAPE thresholds for Cb clouds range from 495 to 2679 J/kg, while TT thresholds for thunderstorms range from 43.5 to 47.4, depending on the seasonal variation (DJF, MAM, JJA, SON). These thresholds demonstrated strong performance in identifying convective weather events, thus serving as a useful reference for forecasting and enhancing flight safety at BIM.

Value–Action Gaps in Students’ Climate Change Literacy: Evidence from a Global South Country

2026-05-25T07:20:45+00:00

This research aims to identify gaps on students’ climate change literacy in Indonesia. We analyse gaps by examining students' knowledge, attitudes/values, and behaviour/actions. This study is a quantitative design with a survey method. A cross-sectional design was employed in this study. We collected 137 high school students in Solok West Sumatra, Indonesia, using paper-based questionnaires. The questionnaires consist of 22 item questions categorised into climate knowledge, attitude/value, and behaviour/action. In this study, the students are knowledgeable about climate change. They believe climate change is real, recognise human activity as the main factor causing it, and know the severe impacts that will occur if climate change continues. Students also have a good attitude towards climate change. However, they have not achieved or changed behaviour or actions that can contribute to climate change. Individual attitudes towards climate change matter. Their daily choices and actions are crucial in climate change management. This research indicates that there is still a value-action gap among the youth. The discrepancy between knowledge and action or value and action gap is an obstacle to achieving the goals of climate change mitigation and adaptation. The two leading causes of this gap are not considering an interdisciplinary approach in teaching climate change and teaching that needs to be action-oriented. Therefore, teaching climate change in an interdisciplinary and action-oriented approach is essential in the school curriculum to deal with this problem.

Ms The Use of Physical Analysis in Assessing the Impact of Anthropogenic Climate Change: A Systematic Literature Review

2025-12-23T08:22:05+00:00

Anthropogenic climate change is the primary cause of modern global warming and one of the greatest scientific challenges of the 21st century. This phenomenon is triggered by increasing concentrations of greenhouse gases (GHGs) such as CO₂, CH₄, N₂O, tropospheric ozone, and changes in aerosols that alter Earth's energy balance. This study aims to identify the latest scientific findings regarding the physical mechanisms that control anthropogenic warming and the Earth system's response to it. The method used is a Systematic Literature Review (SLR) of 30 primary research articles indexed by Scopus, Web of Science, Springer, MDPI, and Sinta (≥2) published in the period 2021–2025. The analysis is based on four research questions (RQs): the contribution of anthropogenic radiative forcing to Earth's Energy Imbalance, changes in atmospheric dynamics, the influence of climate feedbacks, and the response of Earth system components such as the ocean, cryosphere, biosphere, and atmosphere. The SLR results show that the increase in GHGs since the industrial era has resulted in significant positive radiative forcing, causing an increase in heat waves, changes in rainfall patterns, shifts in the jet stream and monsoon, and an intensification of ENSO variability. Furthermore, feedback mechanisms such as increased water vapor, decreased ice albedo, and cloud sensitivity amplify global warming, while carbon release from permafrost and decreased ocean absorption capacity increase long-term climate instability. This research confirms that anthropogenic climate change is an integrated process between the atmosphere, ocean, and biosphere, indicating the potential to reach tipping points. Strengthening climate physics modeling, improving the quality of observations, and integrating scientific findings into evidence-based mitigation policies are needed to prevent the acceleration of climate change in the future.

Analysis of Heavy Rainfall Using Radar Image Data, Satellite Images, and Rainfall Stations in the City of Padang

2026-04-10T04:05:03+00:00

Padang City, as the capital of West Sumatra Province, often experiences heavy rains that can cause flooding and landslides. This phenomenon of heavy rainfall is a matter of serious concern due to its impact on the lives of the community, infrastructure, and the regional economy. On March 7, 2024, heavy rainfall occurred in Padang City, triggering flooding and causing loss of life and property. The analysis was conducted using weather radar imagery, satellite imagery, and rainfall observation data from several rain gauges in Padang City. To obtain representative rainfall data with broad spatial coverage, the use of remote sensing data such as weather radar images and satellite images is vital, especially for areas with a limited number of rain stations or difficult-to-reach topography. Therefore, this study aims to analyze the comparison of rainfall data based on radar imagery, satellite imagery, and rain gauge data to understand the advantages and limitations of each instrument. The combination of these three data sources is very important to improve the accuracy of rainfall monitoring. The research method used in this study is quantitative research using data from the BMKG. The results of the analysis obtained from the error and correlation, both from radar data and satellite imagery, generally show a tendency to underestimate the rainfall observed at rain gauges in Padang City, as indicated by the Mean Error (ME) value, which is predominantly negative at almost all rain gauges.

A Development Of The RegCM5 Climate Model In The World (Systematic Literature Review)

2025-05-19T08:16:46+00:00

Regional Climate Model Version 5 (RegCM5) is one of the climate models
widely used to analyze regional climate dynamics with high resolution.
RegCM5 can predict climate patterns in certain areas by integrating
various atmospheric parameters and interactions between land, ocean, and
atmosphere. This study uses a literature review method used to analyze
literature related to the RegCM5 climate model using the keywords
"Climate Models and RegCM5" on Google Scholar. In this study, a
sampling process was carried out on journals based on the 2020-2024
range so that 21 journals were obtained that were relevant to the topics
discussed in this study.
