lähitermistö

Lähitermistö refers to the air layer closest to the Earth's surface. It is the environment where terrestrial organisms, including humans, plants, and animals, live and interact. This layer is characterized by temperature, humidity, and wind speed variations that are significantly influenced by the underlying surface, such as soil, water, or vegetation. Understanding lähitermistö is crucial in various scientific fields, including meteorology, agriculture, and ecology.

The diurnal and seasonal changes in solar radiation directly impact the temperature and moisture content of the lähitermistö. For instance, during the day, surfaces absorb solar energy and heat the air above them, while at night, surfaces cool and can cool the air. Evaporation from soil and transpiration from plants also release moisture into this layer, affecting humidity levels. Wind plays a vital role in mixing the air within the lähitermistö, transporting heat and moisture, and influencing the exchange of gases between the surface and the atmosphere. Microclimates, which are localized variations in atmospheric conditions, are prominent features of the lähitermistö and can lead to diverse habitats and plant growth patterns even within small areas.
