How often are synoptic observations typically made?

Synoptic observations are made every three hours because this frequency captures essential changes in atmospheric conditions over a range of time. These observations are crucial for weather forecasting and monitoring as they provide timely and relevant data regarding temperature, humidity, wind speed and direction, pressure, and cloud cover among other meteorological phenomena. This three-hour interval allows meteorologists to analyze short-term weather patterns and make predictions about impending weather changes. The consistency and timing of these observations contribute significantly to the accuracy of weather forecasting models and ensure that recent developments in weather conditions are adequately reported and analyzed.
