Kuzeybatı Anadolu'da Hava Tipleri
Abstract
Weather types that were observed in the North-west Anatolian sub-region of Turkey during the period 1988-1995 were examined in the study. Method of determination for weather types in the research area was developed based on different methods of weather types that were used for the various regions of the world. Determination of weather types in the Northwest Anatolia was carried out by interpretations of the synoptic maps (00:00 GMT), atmospheric events and climatic elements. Thirteen weather types that are occurred depending on seven genetic systems were determined for the study area. Different parts of the pressure systems and weather fronts together led to occurring of various weather types. Determined weather types are divided into three groups: a) Annual: front of the mid-latitude depressions; north of the mid-latitude depressions; south of the mid-latitude depressions; middle of the Azores high; north of the Azores high; south of the Azores high. b) Cold period: the Azores high/the Siberian high; middle of the Siberian high; west of the Siberian high; south of the Siberian high. c) Warm period: the Azores high/the Basra low, and the Basra low. Weather types that were determined for the North-west Anatolia has a great ability to explain occurrence of the climatic features and conditions. However, validity of such an approach should be questioned by applying it to different regions of Turkey. If the sufficient data can be reached, it should also be studied for longer periods.
