Welcome to the atmosphere's 'intelligence bureau.' As geographers, our primary task is to transform chaotic atmospheric data into language humans can understand. We decode the atmosphere’s rhythms using a precise system ofdecoder— standardized symbols, satellite cloud images, and weather proverbs that have accumulated wisdom over millennia.

I. Multidimensional Analysis of Weather Language

A complete weather forecast goes beyond just 'clear turning to partly cloudy.' It includes the following core elements:

• Wind Direction and Wind SpeedWind direction refers to the origin of the wind (e.g., northerly wind means wind blowing from the north). Higher wind force numbers indicate stronger wind energy.
• Probability of PrecipitationIt indicates the likelihood of precipitation; higher values mean greater chances of rain or snow.
• Relative HumidityIt represents the percentage of water vapor in the air. Generally, more moisture leads to higher relative humidity and a potentially damp or cool sensation.

II. The Collision of Color and Wisdom

In satellite cloud images (Fig. 7-1-5), colors serve as direct forecasting signals:Green indicates land,blue indicates ocean, whilewhite represents cloud and rain areas. The denser the white, the thicker the cloud layer and the higher the risk of precipitation.

Beyond modern technology, folk wisdom has distilled proverbs through observation. For example, 'swallows flying low' occurs because of low pressure and high humidity before rain, causing insects to fly close to the ground. We constantly use various methods to monitor weather changes for accurate forecasts.
