This shift in humidity is primarily due to the influx of cold air from the Siberian region, which brings moisture along with it.

Impact of Climate Change on Humidity

Climate change is projected to have a profound impact on humidity levels in Osh, Kyrgyzstan. Rising global temperatures are likely to lead to increased evaporation from water bodies, resulting in higher humidity levels. This could potentially intensify the discomfort of residents during the summer months, as the combination of high temperatures and high humidity can create an oppressive and unhealthy environment. Additionally, changes in precipitation patterns could affect the humidity levels, with more frequent and intense rainfall events potentially leading to increased humidity in the region. Understanding and mitigating these changes are crucial for sustainable urban planning and public health initiatives in Osh.

Wind Patterns

The wind patterns in Osh, Kyrgyzstan, are primarily influenced by the topography of the region and the prevailing westerly winds. During the winter months, cold easterly winds from the Tien Shan mountains dominate the region, while in the summer, westerly winds from the Uzbek steppes bring warm and dry air.
