The reliance of weather variation towards insolation pattern in Perlis, Malaysia / Nurull Syamimiey Mohd Rozali

Incoming solar radiation constitutes the Earth's primary energy source. Perlis, Malaysia, undergoes significant weather variations throughout the year, influencing the region's insolation patterns. Given the imperative of climate change and evolving weather patterns, adaptive strategies are essential for effective environmental management. This research aims to investigate the interdependence of weather variations and insolation patterns in Perlis, Malaysia. To achieve this goal, the study's objectives are to determine weather variation and insolation pattern throughout the year 2022 in Perlis and to evaluate the relationship of weather variation and insolation pattern throughout the year 2022 in Perlis. The research initiates with comprehensive data collection, utilizing meteorological data to understand seasonal trends and fluctuations in weather conditions. Concurrently, solar radiation data is meticulously generated using DTM. Statistical analyses, including correlation studies, are then applied to discern potential relationships between meteorological factors and insolation. Anticipated outcomes include understanding seasonal weather patterns and their impact on solar radiation, identifying specific relationships between weather factors and insolation across the region. Temperature and rainfall have a moderate correlation with insolation pattern, with R²= 0.5549 and 0. 5458. The correlation between wind speed and insolation pattern is weak, with R² = 0.0537. The obtained data will be utilized to generate spatial maps employing Geographic Information System (GIS) methodologies, depicting changes in the weather across distinct regions in Perlis. These maps will facilitate localized planning and decision-making processes.
