Coupled processes between the equatorial ocean and atmosphere control the spatial structure of the annualmean state in the Pacific region, in particular the warm pool–cold tongue structure. At the same time, coupled processes are known to be responsible for the variability about this mean state, in particular the El Niño–Southern Oscillation phenomenon. In this paper, the connection between bot...
Historical climatology is defined as a “research field situated at the interface of climato logy and (environmental) history dealing mainly with documentary evidence and using the methodology of both climatology and history” (Brázdil et al., 2005). following the same source, “(i) it aims at reconstructing temporal and spatial patterns of weather and climate, as well as climate related natural ...
Abstract Palaeo-glacial landforms can give insights into bed roughness that currently cannot be captured underneath contemporary-ice streams. A few studies have measured of palaeo-ice streams but the specific landform assemblages has not been assessed. If glacial a characteristic bed-roughness signature, this could potentially used to constrain where certain exist sheets. To test this, was calc...
Winter mixed layer characteristics in the North Pacific Ocean are examined and compared between Argo floats in 2006 and the World Ocean Atlas 2001 (WOA01) climatology for a series of named water masses, North Pacific Tropical Water (NPTW), Eastern Subtropical Mode Water (ESTMW), North Pacific Subtropical Mode Water (NPSTMW), Light Central Mode Water (LCMW) and Dense Central Mode Water (DCMW). T...
Abstract. Evidence for sea-level change during and around Marine Isotope Stage (MIS) 5e (ca. 125 ka) in southern Africa derives from a wide variety of geomorphic sedimentological indicators, supported the past 2 decades by absolute chronological control, particularly on littoral deposits, some which have quantifiable relationship to former sea level. In addition these proxies, data provided bot...
A T-S volumetric census, with a resolution of 0.2°C and 0.1 psu, for years 20-25 of the World Ocean Circulation Experiment Community Modeling Effort eddy-resolving simulation of the equatorial and North Atlantic Ocean, reveals how the thermohalipe character of the model has changed from the initial conditions, which were taken from the Levitus climatology. Any changes in the thermohaline struct...
