In consequence, we conclude that δD p is a correct candidate to examine and to reconstruct large-scale atmospheric processes from past to present time scales.

We show that large-scale dynamic along air masses history is dominant (nearly 80%) to explain δD p whereas local effects are dominant to explain deuterium excess in precipitation. Lastly, we explore how local processes affect δD p. Other local processes such as rain type, condensation conditions and surface water recycling appear as better candidates to explain ΔD p_eq. The review of possible causes to explain the disequilibriums shows that below-cloud rain evaporation and diffusive exchanges are little involved. Although equilibrium state does not prevail at the individual rain event scale, a strong relationship is observed between δD p and δD p_eq over the whole period of field samplings (r 2 = 0.86, n = 70, p < 0.001). They are significantly correlated to δD p (r 2 = 0.30, n = 70, p < 0.001) suggesting that controls on δD p also impact ΔD p_eq. Disequilibriums (ΔD p_eq = δD p - δD p_eq) are mostly negative (73%), indicating that precipitation is more depleted than a condensate that would have been formed from surface water vapor, and half of them are between −10 and + 10‰. Our observations show that the observed isotopic composition of precipitation (δD p) deviates from the theoretical isotopic composition of precipitation at equilibrium with water vapor (δD p_eq). When they get larger than a radius of about 4.5 mm they rapidly become distorted into a shape rather like a parachute with a tube of water around the base - and then they break up into smaller drops.

This study examines the isotopic equilibrium state from event-based precipitation and daily near-surface water vapor samples collected during the onset and the termination of the 2005–2006 wet season in the Bolivian Andes (Zongo valley, 16☀9′S, 68☀7′W). 'Small raindrops (radius < 1 millimeter (mm)) are spherical larger ones assume a shape more like that of a hamburger bun. GitHub - d-harel/raindrops: Query UI plugin for raindrops on water effect. However, the paucity of field observations limits the validation of this assumption. Wash the mask after every use.The isotopic equilibrium state between precipitation and low-level water vapor is a common assumption in numerous paleoclimate and atmospheric studies based on water stable isotopes. After use, remove the mask from behind, loops first.Loop the elastic straps around your ears and adjust the toggles, if available, so there are no gaps between your face and the mask. The WHO recommends that you clean hands with alcohol-based hand rub or soap and water before putting on a mask.Please check with your local authorities for updated requirements and recommendations for wearing cloth face masks. Some governments currently recommend wearing cloth face coverings in public settings where social distancing is difficult (e.g., grocery stores, pharmacies). Please see our Help Center for more details. Masks can be returned within 14 days of receiving your order. Younger children ages 3 and up should wear appropriately sized Kids’ masks. Fitted and Flat masks should only be worn by people ages 13 and up.
