| Zusammenfassung |
| The climate characteristics of summer human thermal discomfort in Athens and
its connection to atmospheric circulation are studied for the period
1954–2012. The human thermal discomfort is examined in terms of the
Predicted Mean Vote (PMV) discomfort index for calm and light wind
(3 ms-1) conditions. Its inter-annual variability is characterised
by a significant increase from the middle 1980s to the end of the study
period. The onset and the cessation of the discomfort period are found to
take place around the beginning of July and the end of August respectively,
but from middle 1980s the dates of onset and cessation have slightly moved
earlier and later, respectively, leading to a longer summer discomfort
period. The connection between human thermal discomfort and atmospheric
circulation is studied by examining the distribution of discomfort cases
across six objectively defined circulation types over Europe, based on Athens
weather characteristics. High values of the PMV discomfort index are mainly
associated with two typical high-summer pressure patterns with the intensity
of discomfort depending on the pressure gradient over the Aegean Sea. On the
contrary, low PMV discomfort index values prevail mainly on days typified by
the other four circulation types, which are more frequent during May, June,
and September. |
