How do we know when it will rain? 我們怎麼知道什麼時候下雨？

• If temperature and dewpoint are the same, the relative humidity will be 100%, which means precipitation 如果溫度和露點相同，則相對濕度將為100％，這意味著沉澱

• If temperature is the same as the air pressure, the relative humidity will be low, which means precipitation 如果溫度與氣壓相同，則相對濕度會很低，這意味著有降水

• High pressure systems tell us that we can expect precipitation 高壓系統告訴我們可以預期會有降水

• If there is 100% cloud cover (overcast skies), the relative humidity will be high, which means precipitation 如果有100％的雲層（多雲的天空），則相對濕度會很高，這意味著有降水
