Data collected by the International Arctic Buoy Programme from 1979 to 1998 are analyzed to obtain statistics of sea level pressure (SLP) and sea ice motion (SIM). The annual and seasonal mean fields agree with those obtained in previous studies of Arctic climatology. The data show a 3-hPa decrease in decadal mean SLP over the central Arctic Ocean between 1979–88 and 1989–98. This decrease in S...

Abstract We investigate the uncertainty (i.e., inter-model spread) in future projections of boreal winter climate, based on forced response ten models from CMIP5 following RCP8.5 scenario. The sea level pressure (SLP) is large North Pacific, Atlantic, and Arctic. A major part these uncertainties (31%) marked by a pattern with center northeastern Pacific dipole over Atlantic that we label as Pac...

We develop a statistical model to predict June-July-August (JJA) daily maximum 8-h average (MDA8) ozone concentrations in the eastern United States based on large-scale climate patterns during the previous spring. We find that anomalously high JJA ozone in the East is correlated with these springtime patterns: warm tropical Atlantic and cold northeast Pacific sea surface temperatures (SSTs), as...

[1] The annual and interannual variations of sea level pressure (SLP) over the Southern Ocean are investigated using the NCEP/NCAR reanalysis data from 1968 to 2005. Results show that the weakening of the Semiannual Oscillation (SAO) has continued to present day but does not occur homogeneously across all longitudes. While the second harmonic of SLP has decreased over the South Pacific Ocean, i...

Abstract Seasonal variability of the ocean bottom pressure (OBP) in world oceans is investigated using 15 years GRACE observations and a Pressure Coordinate Ocean Model (PCOM). In boreal winter, negative OBP anomalies appear northern North Pacific, subtropical South Pacific north 40 °S Indian Ocean, while anomaly Southern positive. The summer pattern opposite to that winter. centers positive (n...

In this study, temporal and spatial trends of sea surface temperature (SST), wind speed, air temperature, salinity (SSS), sea-level pressure (SLP), SST-based upwelling index are examined compared with data from previous studies. Analyses these parameters performed for five critical locations that best illustrate the characteristic meteorological oceanographic structures Aegean Sea. Upwelling ca...

Vegetation productivity trends for the Arctic tundra are updated for the 1982–2011 period and examined in the context of land surface temperatures and coastal sea ice. Understanding mechanistic links between vegetation and climate parameters contributes to model advancements that are necessary for improving climate projections. This study employs remote sensing data: Global Inventory Modeling a...

[1] Annual cycle, one of the principle modes in the variability of the air-sea system, can be analyzed using tide analysis tools for extending the concept of oceanic tidal amphidromes to the atmosphere. In this paper, the annual phase-amplitude characteristics of two variables, sea-level pressure (SLP) and precipitation, were investigated to explore the annual atmospheric amphidromes on a globa...

The relationship between precipitation and large-scale measures of atmospheric circulation has received much attention in recent years (e.g. Bardossy & Caspary, 1990; Bardossy & Plate, 1992; Hughes et al., 1993; Woolhiser et al., 1993; Katz & Parlange, 1993). Some of the interest relates to quantifying the possible change in atmospheric circulation within the past two decades, with associated c...

Outlet glaciers draining the Antarctic Ice Sheet into the Amundsen Sea 1 Embayment (ASE) have accelerated in recent decades, most likely as a result of increased 2 melting of their ice shelf termini by warm Circumpolar Deep Water (CDW). An ocean 3 model forced with climate reanalysis data shows that, beginning in the early 1990s, an 4 increase in westerly wind stress over the continental shelf ...
