“…The deviation of measured slopes from the expectations suggests that most of the precipitation has undergone raindrop evaporation effect (Clark and Fritz, 1997;Aragua´s-Aragua´s et al, 1998;Peng et al, 2010). The stations with the largest deviations appear in groups III (1.73Á2.45) and II (0.26Á1.80).…”

A B S T R A C T During the mid-1980s, there were 31 stations in China that successfully participated in the Global Network of Isotopes in Precipitation. However, most observations were suspended after the mid-1990s. The discontinuous data hindered the application of precipitation isotopes, which are strongly affected in China by the Asian monsoon and are thus of intrinsic interest for palaeoclimatologists. Therefore, to continuously observe precipitation isotopes nationwide, the Chinese Network of

“…In the studies presented by Gonfiantini et al (2001) and Peng et al (2010), a seasonality of the altitude effect is reported. Both studies were also carried out in tropical environments with a similar altitudinal air temperature gradient (0.61 • C × 100 m −1 in our study area; Gonfiantini et al, 2001, 0.42-0.55 • C × 100 m −1 ; Peng et al, 2010, 0.53-0.65 • C × 100 m −1 ).…”

“…For the on-site amount effect we assume that events with a higher amount of precipitation and the same history will yield an overall lighter isotopic composition than events with smaller amounts of rainfall. However, recent studies give rise to the assumption that factors other than the amount of precipitation or the origin of the air masses play an important role in controlling seasonal patterns of isotope signatures (Breitenbach et al, 2010;Feng et al, 2009;Kebede and Travi, 2011;Lee et al, 2009;Peng et al, 2010;Rhodes et al, 2006;Risi et al, 2008a,b;Scholl et al, 2009;Villacís et al, 2008;Vimeux et al, 2005Vimeux et al, , 2011. For example, Rhodes et al (2006) and Scholl et al (2009) concluded that orographic precipitation during the trade wind dominated dry season is enriched compared to the mostly convective precipitation type during the wet season occurring, e.g.…”

“…Despite being of orographic nature as well, this precipitation is not characterized by recycled moisture. To further investigate and strengthen our assumption that recycled moisture from the Amazon Basin is causing the high isotopic composition during trade wind-related precipitation events, we used the deuterium excess parameter to assess the actual amount of recycled moisture (Araguas-Araguas et al, 2000;Bowen and Revenaugh, 2003;Froehlich et al, 2002;Gat, 2000;Liu et al, 2007;Njitchoua et al, 1999;Peng et al, 2010;Victoria et al, 1991). For trade wind-related precipitation events, deuterium excess averages 14.9 ‰ and hence, is significantly higher than for other events (d = 9.6 ‰).…”

“…On catchment scales, the altitude effect is an important measure for the spatial variability, especially in mountainous catchments that cover high altitudinal ranges. It has therefore been the topic of various studies conducted around the world (Cortés et al, 1997;Garcia et al, 1998;Gonfiantini et al, 2001;Kattan, 2006;McGuire et al, 2005;Peng et al, 2010;Scholl et al, 2009;Siegenthaler and Oeschger, 1980;Vimeux et al, 2005Vimeux et al, , 2011Vogel et al, 1975;Yurtsever and Gat, 1981). Most of the reported lapse rates for δ 18 O and δ 2 H lie in ranges of…”

Abstract. This study presents the spatial and temporal variability of δ 18 O and δ 2 H isotope signatures in precipitation of a south Ecuadorian montane cloud forest catchment (San Francisco catchment). From 2 September to 25 December 2010, event sampling of open rainfall was conducted along an altitudinal transect (1800 to 2800 m a.s.l.) to investigate possible effects of altitude and weather conditions on the isotope signature.The spatial variability is mainly affected by the altitude effect. The event based δ 18 O altitude effect for the study area averages −0.22 ‰ × 100 m −1 (δ 2 H: −1.12 ‰ × 100 m −1 ). The temporal variability is mostly controlled by prevailing air masses. Precipitation during the times of prevailing southeasterly trade winds is significantly enriched in heavy isotopes compared to precipitation during other weather conditions. In the study area, weather during austral winter is commonly controlled by southeasterly trade winds. Since the Amazon Basin contributes large amounts of recycled moisture to these air masses, trade wind-related precipitation is enriched in heavy isotopes. We used deuterium excess to further evaluate the contribution of recycled moisture to precipitation. Analogously to the δ 18 O and δ 2 H values, deuterium excess is significantly higher in trade wind-related precipitation. Consequently, it is assumed that evaporated moisture is responsible for high concentrations of heavy isotopes during austral winter.

Rainouts over the Arabian Sea and Western Ghats during moisture advection and recycling explain the isotopic composition of Bangalore summer rains

Variations in the isotope ratios (18O/16O and D/H) of meteoric water at continental stations serve as valuable tracers for the hydrological cycle. In the present study, we investigated the role of sea surface temperature, wind speed, relative humidity, and rainout processes on the stable isotopic composition of the 2010 monsoon rainwater of Bangalore. The wind over the ocean influences the sea surface temperature and humidity which in turn influence the vapor isotopic composition. The rainout over the Arabian Sea and the land mass (Western Ghats) during advection of the air parcel to Bangalore and its recycling further modify the vapor composition. The isotopic ratios (δ18O, δD, and d‐excess) of the precipitation at Bangalore was estimated following a Rayleigh fractionation model involving rainout and recycling processes yield values consistent with our observation. In some samples, however, the observed isotopic ratios are higher (by 2 to 5‰), and a few of them are associated with high d‐excess values. These discrepancies could be due to limitation of the model assumptions.
