However, rarely inhabited terrains, as well as the presence of extremely high values
of humidity in the air should not be disregarded.
Which areas are going to be under the effect of the SW stream will depend on
the angle (as well as other physical-chemical characteristics) under which the SW
stream penetrates towards the surface over the tropics. From the previously men-
tioned case, there has also been the time coincidence of air mass moving from the
southwest towards the Balkans. It is very important to emphasize that before the
destructive power of fires occurred in the southeastern Europe, a series of fires had
occurred in the northwestern Africa, as well as on many locations of the European
Mediterranean (Gomes et al., 2009 ).
Figure 2.3 shows mean wind speeds, approximately from the upper border of
the troposphere to some mountain peaks. Yellow lines mark wind speeds, so that
by following their location we can make some conclusions on dominant directions
of air mass moving. The upper part of the 3 relates to July 21, while the lower
one to July 22, 2007. The same day when satellite measured the sudden rise, i.e.
IMF approaching towards Earth, the isoclines of the increased mean wind speed
(70 knt) were recorded in the area of the Mediterranean. According to heliocentric
hypothesis, the penetration occurred over the Atlantic geomagnetic anomaly, so that
a part of stream was directed towards Europe. Gomes and Radovanovic ( 2008 )for
the first time, in the case of Portugal, explained the idea according to which the
air masses took hold due to SW penetration over the Atlantic anomaly. Based on
the available literature, it seems that the research of the links between processes on
