<abstract>
<p>The sea breeze (SB) is a thermally induced boundary layer phenomenon that
occurs at coastal locations throughout the world. Previous satellite remote
sensing studies used low-level clouds formed over the sea-breeze convergence
zones to identify the SB. In this study continuous thermal infrared data
from a geostationary satellite (Meteosat Second Generation) and concurrent
field measurements were used to detect and characterize the SB in clear sky
conditions during the summer. Surface data (wind speed and direction) from
11 sites over Israel for ten summer days in July 2010 for three different
synoptic circulation categories were selected.
&lt;br&gt;&lt;br&gt;
In order to assess the impact of the synoptic induced flow on the SB, we
looked for the best agreement between surface and satellite SB timing. An
independent classification of synoptic categories performed for the ten
summer days revealed two distinct patterns of the SB. During weak horizontal
pressure gradient (Weak Persian Trough and High to the West), which enables
full development of the SB, the timing of the SB from satellite and field
measurements were well correlated (&lt;i&gt;R&lt;/i&gt;&lt;sup&gt;2&lt;/sup&gt; = 0.75), as compared to
unfavorable atmospheric conditions (Deep Persian Trough) yielding lower
value (&lt;i&gt;R&lt;/i&gt;&lt;sup&gt;2&lt;/sup&gt; = 0.5). The SB was identified by surface measurements in an
earlier time of the day, with respect to the satellite column integrated
measurements.
&lt;br&gt;&lt;br&gt;
Visualizing timing of the SB retrieved from satellite data enabled
distinction of SB behavior under different synoptic categories. Over desert
regions the strong thermal contrast enables detection of the SB even under
suppressing synoptic conditions (Deep Persian Trough).
&lt;br&gt;&lt;br&gt;
This method enables detection and timing of the SB over desert regions where
clouds and field measurements are scarce, and is applicable worldwide.</p>
