Kõrgusjärg

Kõrgusjärg is an Estonian term that translates to "height order" or "altitude sequence". It is commonly used in meteorology and geography to describe the arrangement of atmospheric layers or geographical features based on their vertical elevation. In meteorology, kõrgusjärg refers to the different temperature profiles and pressure gradients that exist at various altitudes within the Earth's atmosphere, such as the troposphere, stratosphere, mesosphere, and thermosphere. Understanding the kõrgusjärg is crucial for weather forecasting and the study of atmospheric phenomena. Geographically, kõrgusjärg can refer to the succession of vegetation zones or climate types that appear as one ascends a mountain range. For example, a mountain might have a kõrgusjärg of deciduous forest at lower elevations, followed by coniferous forest, then alpine meadows, and finally snow and ice at the highest altitudes. This concept helps in understanding ecological zonation and how environmental conditions change with elevation. The term emphasizes a hierarchical structure dictated by vertical position.
