An anticyclone is a large area of high air pressure. Air in the middle of it slowly sinks, and the weather underneath is often calm: clearer skies, lighter wind, and usually dry.

An anticyclone is a large area of high air pressure anticyclone是一大片高氣壓區. Air in the middle of it slowly sinks中間的空氣會慢慢下沉, and the weather underneath is often calm底下的天氣通常比較平靜: clearer skies, lighter wind, and usually dry天空較晴朗、風較弱，通常也比較乾.

Weather presenters more often just say high pressure; anticyclone is the science word for the same kind of system. A cyclone is the other way round — low pressure, and often rain or storms — and this word was built as the opposite of that. Sir Francis Galton coined it in the 1860s.

Weather presenters more often just say high pressure氣象主播比較常直接說high pressure（高壓）; anticyclone is the science word for the same kind of system anticyclone是同一種系統的科學用詞. A cyclone is the other way round cyclone（氣旋）正好相反 — low pressure, and often rain or storms低氣壓、常常有雨或風暴 — and this word was built as the opposite of that而這個字就是造來當它的反義詞. Sir Francis Galton coined it in the 1860s高爾頓爵士在1860年代創造了這個字.

Though actually the weather is not always pleasant. A summer anticyclone can sit still and give a heatwave; a winter one can bring fog or a hard frost. In the northern half of the world the wind around it moves in a clockwise ring; south of the equator it goes the other way.

Though actually不過事實上, the weather is not always pleasant天氣不見得總是宜人. A summer anticyclone can sit still and give a heatwave夏天的anticyclone可能會停滯不動、帶來熱浪; a winter one can bring fog or a hard frost冬天的則可能帶來霧或嚴重的霜凍. In the northern half of the world在北半球, the wind around it moves in a clockwise ring它周圍的風是順時針轉的; south of the equator it goes the other way赤道以南則反過來.

You will meet the word on weather maps and in geography, not much in everyday chat.

You will meet the word on weather maps and in geography你會在天氣圖和地理課裡看到這個字, not much in everyday chat日常聊天不太會用到.
