An observational study of the summer Mediterranean Sea breeze front penetration into the complex topography of the Jordan Rift Valley

摘要

The Mediterranean summer sea breeze front (SBF) climatic features of penetration into the complex topography of the Jordan Rift Valley (JRV) were investigated. It was shown that the SBF penetration into the JRV occurs in a well-defined chronological order from north to south. One exception to this general rule is the breeze penetration of Sdom, which occurs after it has penetrated the Arava which is located further south, probably due to the micro-climatic effect of the Dead Sea. It was also noted that the breeze increases the local specific humidity as it reaches the JRV in spite of significant temperature increases. The temperature reaches its daily peak 2 to 3 h later in the southern valley compared to the northern valley and is suggested to be due to the later SBF penetration and the valley structure. The pre-SBF line features in the JRV are described.
