... deserts are characterized by lowest relative humidity and cloudiness; the amount of low frequency rainfall, monthly and yearly average temperature, the change of high daily temperature and intensive winds. (Atalay, 2010:36) (Figure 1). On a global scale, in the north hemisphere, the regions with the main dust sources are the west coast of South Africa, Central Asia, and the Middle East. ...

... 9) it is believed that Bodele depression is not only the most important dust emission source in Sahara region but all over the world. At the time of Holocene and Pleistocene is said that Diatomite storage covers a large place in Chad Lake ( Figure 10). Diatomite is a very soft matter. ...

... diameter of an advanced, mature middle latitude cyclone is at least 1600 km. Middle latitude cyclones move with high atmosphere west winds in the counter clockwise from west to east, from jet flows to Rossby mountains (Türkeş, 2010: 443) (Figure 11). The intense depressions in Morocco, Libya and Algeria drag the dust sets to middle Mediterranean, and Atlantic. ...

... dust storms in Egypt are related to depressions areas and facades area in Mediterranean and the west of North Africa. (Goudie & Middletion, 2006: 25) (Figure 12). there are some needed conditions for the long way transportation of the deserts dusts to higher troposphere. ...

... cyclones mostly happen in 35-70 degree Latitude. The transportation of dust to Mediterranean Basin and Turkey stops, when these cyclones happen ( Figure 13). But when these cyclones happen in 30 degree latitude the several collective movements and turbulence from Sahara desert come with intensity to Mediterranean Basin and Turkey. ...

... winds that show their effects in summer occur because of the terrestrial tropical air masses that come from Sahara Desert and Arabian Peninsula (Atalay, 2010: 194). One of these winds is Scirocco, the hot and arid wind that comes from the north of Big Sahara to Algeria, Tunis, Spain, and Italia coasts (Figure 15). When the pressure in Mediterranean basin falls we consist of an anticyclone in Sahara Desert. ...

... as Scirocco, Hamsin is a hot, arid and full of dust wind that flows to Egypt and Libya coasts (Figure 15).In the period between February and May, the pressure in East Sahara is high and in East Mediterranean is low. Hamsin flows to south because of this pressure and carries dusts with the air masses. ...

... condition makes arid air masses dominate Mediterranean basin .. At the negative phase of NAO the difference between pressures in Azores and Island becomes less evident and West Winds reduce. That's why Mediterranean basin is more affected by the systems that bring rain in the North Atlantic (Figure 16). ...
Context 10
... the work named Dayan (2007) is observed that the transportation and storage of dusts in southeast Atlantic are related to NAO. This work indicates the fact that at the positive phase of NAO because of the low effect of positive cyclone in Mediterranean areas, the dust activity is low as well, and the opposite at the negative phase ( Figure 17). ...

Plain Language Summary
Sahara Desert has experienced a stronger warming than the tropical land on average since 1979. Debates continue on whether the amplified Saharan warming is a response to the remote sea surface temperature (SST) change or the radiative forcing brought about by the increasing anthropogenic greenhouse gas. In this study, we quan...
