  "description": "Abstract. We present new data on the 4.2\u2009ka event in the central Mediterranean from\nCorchia Cave (Tuscany, central Italy) stalagmite CC27. The stalagmite was\nanalyzed for stable isotopes (\u03b413C and \u03b418O)\nand trace elements (Mg, U, P, Y), with all proxies showing a coherent phase\nof reduced cave recharge between ca. 4.5 and 4.1\u2009ka\u2009BP. Based on the\ncurrent climatological data on cyclogenesis, the reduction in cave recharge\nis considered to be associated with the weakening of the cyclone center\nlocated in the Gulf of Genoa in response to reduced advection of air masses\nfrom the Atlantic during winter. These conditions, which closely resemble a\npositive North Atlantic Oscillation (NAO) type of configuration, are\nassociated with cooler and wetter summers with reduced sea warming, which\nreduced the western Mediterranean evaporation during autumn\u2013early winter,\nfurther reducing precipitation.",
