The term "seasonal variations" refers to changes in weather patterns, temperature or other atmospheric conditions that occur on a regular basis throughout the year. These variations can be attributed to natural factors such as changes in solar radiation, Earth's axial tilt and ocean currents, among others. Seasonal variations are also influenced by human activities such as agriculture, forestry, urbanization or industrial processes which may alter local climate conditions.
In meteorology, seasonal variations refer to the predictable fluctuations in weather patterns that occur annually due to changes in Earth's position relative to the sun and other celestial bodies. These variations result in different climatic conditions such as temperature, precipitation or humidity levels which affect ecosystems, agriculture, human health and many other aspects of life on earth.
In summary, seasonal variations refer to changes in weather patterns that occur regularly throughout the year due to natural or human factors, impacting various aspects of our lives.
