Abstract. Maud Rise polynyas (MRPs) form due to deep convection, which is caused by static instabilities of the water column. Recent studies with Community Earth System Model (CESM) have indicated that a multidecadal varying heat accumulation in subsurface layer occurs prior MRP formation transport over Weddell Gyre. In this study, conceptual box model, forced CESM data, used investigate role f...

Quantifying temporal variation in demographic rates is a central goal of population ecology. In this study, we analyzed multidecadal age-structured time series Arctic char (Salvelinus alpinus) abundance Lake Mývatn, Iceland, to infer the time-varying response reduced harvest wake fishery’s collapse. Our analysis shows that while survival probability adults increased following alleviation harves...

A hydroclimatology, or description of long-term means and interannual variation, that focuses on soil moisture deficits was constructed for the period of 1895–1998 for a six-state region composing the Ohio Valley. The term ‘‘deficit’’ is considered from an agricultural point of view whereby moisture-induced crop stress is a combination of insufficient precipitation and soil moisture. Of particu...

A worldwide climatology of the diurnal cycles of low clouds is obtained from surface observations made eight or four times daily at 3or 6-h intervals from weather stations and ships. Harmonic fits to the daily cycle are made for 5388 weather stations with long periods of record, and for gridded data on a 58 3 58 or 108 3 108 latitude–longitude grid over land and ocean areas separately. For all ...

Coral skeletons contain records of past environmental conditions due to their long life span and well calibrated geochemical signatures. C and O isotope records of corals are especially interesting, because they can highlight multidecadal variability of local climate conditions beyond the instrumental record, with high fidelity and sub-annual resolution. Although, in order to get an optimal geo...
