|a Global warming increases the occurrence probability of hot
extremes, and improving the predictability of such events is thus
becoming of critical importance. Hot extremes have been shown to
be induced by surface moisture deficits in some regions. In this
study, we assess whether such a relationship holds at the global
scale. We find that wide areas of the world display a strong relationship
between the number of hot days in the regions’ hottest
month and preceding precipitation deficits. The occurrence probability
of an above-average number of hot days is over 70% after
precipitation deficits in most parts of South America as well as the
Iberian Peninsula and Eastern Australia, and over 60% in most of
North America and Eastern Europe, while it is below 30–40% after
wet conditions in these regions. Using quantile regression analyses,
we show that the impact of precipitation deficits on the number
of hot days is asymmetric, i.e. extreme high numbers of hot
days are most strongly influenced. This relationship also applies
to the 2011 extreme event in Texas. These findings suggest that
effects of soil moisture-temperature coupling are geographically
more widespread than commonly assumed. |
