Yuliarti, A., Simanjuntak, P. P., & Ardiani, N. (2023). Identifying trends in extreme climate patterns in Pangkalpinang. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 417-427). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Human activities have led to an increase in global temperatures. This also increases the frequency of extreme climates such as extreme rainfall and air temperatures. Pangkalpinang City is the capital of the Bangka Belitung Islands Province. The growth rate of Pangkalpinang city is approximately 1.1% per year, with a 29% increase in the number of vehicles being one of the factors contributing to the rise in extreme climate events. This research aimed to examine the trends in extreme air temperatures and extreme rainfall in Pangkalpinang city during the period of 1991-2022. The research method used is secondary data research with a quantitative approach. The study utilized 12 extreme climate indices as defined by ETCCDMI, comprising 7 extreme air temperature indices and 5 extreme rainfall indices. The significant extreme air temperature trend indicates an increase in air temperature in Pangkalpinang, especially the annual average daily maximum temperature of 0.018°C/year, the annual average daily minimum temperature of 0.025°C/year, while the TN10P (Cold night) index experienced a decrease of 0.344°C/year which is the opposite of the TX90p (Warm Days) index trend of 0.273°C/year. The rainfall trend in Pangkalpinang has not changed significantly.

Abstract

Climate-based tourism is closely linked to atmospheric comfort, while ongoing global climate change has intensified uncertainty in climatic conditions across many tourism destinations, including tropical geoparks. This study evaluates the spatial and temporal patterns of tourism climate comfort in the Belitung Geopark by integrating historical climate data (1991–2024) and future climate projections (2026–2050) under the Representative Concentration Pathway (RCP) 4.5 scenario. Tourism climate comfort was assessed using the Tourism Climate Index (TCI), which incorporates key meteorological variables, namely air temperature, relative humidity, precipitation, wind speed, and solar radiation. A spatial–temporal analysis supported by Geographic Information Systems (GIS) and heatmap visualization was applied to examine variations across 17 geosites. The results reveal a pronounced seasonal pattern characteristic of tropical climates, with the highest TCI values occurring during the dry season, particularly in August and September. Coastal geosites consistently exhibit higher and more stable comfort levels than inland, hilly, and forested areas, which experience noticeable declines in comfort during the wet season due to increased rainfall and humidity. Climate projections indicate a general reduction in TCI values, especially during transitional and wet months; however, most coastal geosites remain within acceptable to good comfort categories for tourism activities. These findings highlight the role of geographical factors, such as proximity to the coast and local atmospheric dynamics, in shaping spatial variations in tourism climate comfort. The study provides a scientific basis for adaptive tourism management, seasonal tourism planning, and climate change adaptation strategies in tropical geopark destinations, it offers potential applications in geography education and spatial climate analysis.
