Abstract: The precipitation record of Kvísker, SE-Iceland (293 mm/24 hrs) is investigated. Kvísker is located downstream of a 2119 m high mountain and observations indicate that strong wind upstream of the mountain is a key factor in generating the maximum precipitation intensity within the 24 hours period. A numerical simulation of the flow suggests that there are two distinct maxima in the precipitation intensity. One is situated close to the mountain top and is directly associated with the updraft and high concentration of liquid cloud water. The second maximum is located downstream and is associated with localized downdrafts and horizontal convergence of the spillover rain.
