Climate for Station: Poorman Alaska, Alaska, United States
Loading live weather...
Climate Analysis & Overview
Poorman, Alaska, located along the Iditarod National Historic Trail, is experiencing a cooling trend, with both high and low temperatures decreasing over the past decade and all-time records. Despite this, the region has recorded extreme temperatures, with a maximum of 36.7°C (98.1°F) and a minimum of -45.6°C (-50.1°F). The absence of a Precipitation Concentration Index (PCI) suggests a gap in monitoring precipitation patterns.
Chilling Trends in Poorman
Poorman, Alaska, situated at 64.105°N, -155.5583°W, finds itself in a subarctic climate zone, characterised by long, cold winters and short, mild summers. The local geography, including its proximity to the Iditarod National Historic Trail, influences its climatic conditions, with vast stretches of tundra and boreal forests. Over the past decade, Poorman has experienced a noticeable cooling trend, with high temperatures falling by 2.57°C (4.63°F) and low temperatures decreasing by 2.29°C (4.13°F). These trends are more pronounced than the all-time cooling trends, where highs have fallen by 0.19°C (0.34°F) and lows by 0.16°C (0.29°F). This consistent cooling pattern suggests a significant shift in the region's thermal dynamics.
Temperature Extremes
Despite the cooling trends, Poorman has recorded some extreme temperatures. The highest temperature ever recorded is 36.7°C (98.1°F), while the lowest is a frigid -45.6°C (-50.1°F). These extremes highlight the variability and potential for significant temperature swings in the region, typical of subarctic climates. Such extremes can have profound impacts on local ecosystems and human activities, particularly in areas reliant on seasonal patterns for subsistence and transport.
Precipitation Monitoring Gaps
The Precipitation Concentration Index (PCI) for Poorman is currently unavailable, indicating a gap in the monitoring of precipitation patterns. The PCI is a measure of how precipitation is distributed over time; a higher PCI suggests precipitation is concentrated in fewer, more intense events, while a lower PCI indicates a more even distribution. The absence of this data means there is limited understanding of how precipitation patterns may be changing in Poorman, which is crucial for water resource management and planning in the face of climate change.
Regional Climate Context
The cooling trends observed in Poorman occur against the backdrop of broader climate goals in the United States, which aim to mitigate climate change impacts through emission reductions and sustainable practices. Understanding localised climate shifts, such as those in Poorman, is essential for informing regional climate adaptation strategies. These trends also underscore the importance of comprehensive climate monitoring to fill existing data gaps and support informed decision-making.
