Synoptic scale meteorology<\/em>:<\/p>\n

In\u00a0meteorology<\/a>, the\u00a0synoptic scale<\/b>\u00a0(also called the\u00a0large scale<\/b>\u00a0or\u00a0cyclonic scale<\/b>) is a\u00a0horizontal<\/a>\u00a0length scale<\/a>\u00a0of the\u00a0order<\/a>\u00a0of 1,000\u00a0km (620\u00a0mi) or more.[<\/span>1]<\/span><\/a><\/sup>\u00a0This corresponds to a horizontal scale typical of\u00a0mid-latitude<\/a>\u00a0depressions<\/a>\u00a0(e.g.\u00a0extratropical cyclones<\/a>). Most\u00a0high-<\/a>\u00a0and\u00a0low-pressure areas<\/a>\u00a0seen on\u00a0weather maps<\/a>\u00a0(such as\u00a0surface weather analyses<\/a>) are synoptic-scale systems, driven by the location of\u00a0Rossby waves<\/a>\u00a0in their respective hemisphere. Low-pressure areas and their related frontal zones occur on the leading edge of a trough within the Rossby wave pattern, while\u00a0high-pressure areas<\/a>\u00a0form on the back edge of the trough. Most\u00a0precipitation<\/a>\u00a0areas occur near frontal zones. The word\u00a0synoptic<\/a><\/i>\u00a0is derived from the\u00a0Ancient Greek<\/a>\u00a0word\u00a0\u03c3\u03c5\u03bd\u03bf\u03c0\u03c4\u03b9\u03ba\u03cc\u03c2<\/a><\/span>\u00a0(sunoptik\u00f3s<\/i><\/span>), meaning “seen together”.

Ryan Hall<\/a>, an Internet weather analyst and owner of a lovely voice, uses synoptic<\/em> frequently in his discussions of weather forecasts, such as this one here.<\/p>\n
