Short Introduction on Thermal Anomaly – Chapter – The Atmosphere, Topic – Thermal Anomaly – World Geography
A thermal anomaly refers to a deviation from the normal or expected temperature pattern in a given region. These anomalies can be either positive (higher than normal temperatures) or negative (lower than normal temperatures) and are crucial indicators of climatic changes and irregularities in weather behavior. They are caused by several natural and anthropogenic factors such as ocean currents, El Niño and La Niña events, greenhouse gas emissions, and urbanization. Monitoring thermal anomalies is essential for climate forecasting, agriculture, environmental planning, and disaster management.
