Climate for Station: Uttaradit, Thailand

Uttaradit is experiencing a warming trend, with both high and low temperatures rising over the past decade. Precipitation patterns have become more evenly distributed, suggesting a shift in local climate dynamics.

Tropical Climate Dynamics

Uttaradit, located at coordinates 17.617, 100.1, falls under the Tropical Savanna climate classification (Aw) in the Köppen system. This region experiences distinct wet and dry seasons, influenced by the monsoon winds. The local geography, characterised by its proximity to the Nan River and surrounding hills, plays a crucial role in shaping its climate patterns. Over the past decade, the highs have increased by 0.08°C (0.14°F), while the lows have shown a more pronounced rise of 0.47°C (0.84°F). These figures suggest a trend towards warmer nights, which could impact local agriculture and water resources.

Long-term Temperature Trends

The all-time temperature trends for Uttaradit indicate a consistent warming pattern. Highs have risen by 0.06°C (0.11°F), and lows by 0.34°C (0.61°F). This warming trend aligns with broader regional climate changes observed across Thailand, where increasing temperatures have been linked to global climate change. The record high temperature for the region stands at 44.5°C (112.1°F), while the record low is 4.5°C (40.1°F), showcasing the temperature extremes experienced in this area.

Precipitation Patterns and PCI

The Precipitation Concentration Index (PCI) provides insight into how rainfall is distributed throughout the year. A decrease in PCI from a baseline of 16.2 to a current value of 14.1 indicates that precipitation in Uttaradit is now more evenly spread across the year. This shift could mitigate the risks of flooding during the monsoon season and droughts during the dry season, reflecting a potential adaptation to changing climate conditions.

Implications for Regional Climate Goals

Thailand's regional climate goals focus on adapting to and mitigating the impacts of climate change. The warming trends observed in Uttaradit, especially the significant rise in nighttime temperatures, could challenge these goals by affecting energy consumption, agricultural productivity, and water management. However, the more even distribution of rainfall could offer some resilience against extreme weather events. Understanding these localised changes is crucial for developing targeted strategies to address the impacts of climate change in the region.
