“…All wind speeds were adjusted to 10 m winds in this study, in consideration of atmospheric stability (Kutsuwada, 1998), to remove this trend. The anemometer installation height for 1973 to 1997 is documented in WMO publication 47 (WMO47;World Meteorological Organization, 1973.…”

Data for the 20th century from the International Comprehensive Ocean and Atmosphere Data Set and the Kobe Collection have been used as input data for global objective analyses of sea-surface temperatures (SSTs) and other marine meteorological variables. This study seeks a better understanding of the historical marine meteorological data and an evaluation of the quality of the data in the Kobe Collection. Objective analyses yield gridded data that are less noisy than observed data, which facilitates handling of historical data. The observed data determine the quality of the objective analyses, and quality control specified for historical data is incorporated into the objective analysis to reduce artificial errors. The objective analyses are based on optimum interpolation and reconstruction with empirical orthogonal functions. The final database produced in this study not only contains analysed values, but also analysis errors and data distributions at each time step of the objective analyses.The analysis database contains ample information on historical observations, as well as signals of marine climate variations during the century. Time series of global mean marine temperatures and cloud cover include trends linked to global warming, and local peaks appear commonly in all the time series around the 1940s. Sea-level pressure and seasurface wind fields show significant linear trends at high latitudes and over the North Pacific Ocean respectively. These trends seem to be artificial. An SST analysis used widely in climatological studies was verified against HadISST from the Hadley Centre and an SST analysis derived from satellite and in situ observations. El Niño and southern oscillation indices for the century are successfully reproduced, even though observations in the tropics are much rarer before 1950 than after 1950.

“…Even though both the J-OFURO and the IFREMER products are derived from QSCAT data, no similar spike signals were found in the time series data from the J-OFURO product. This meant that spike signals had been removed during the data conversion process using the weighted average method (Kutsuwada 1998). Thus, when comparing time series data from the J-OFURO and IFREMER products, we observed spike signals that were random and had no clear time dependence.…”

“…Gridded products of surface wind/wind-stress vectors covering the global ocean have been developed using satellite scatterometer (QSCAT/SeaWinds) data and the weighted average method (Kutsuwada 1998;Kubota et al 2002); the products are called J-OFURO (http://dtsv.scc.u-tokai. ac.jp/j-ofuro/index.html).…”

“…We used the L2B12 (level-2) data products provided by NASA JPL PO.DAAC (ftp://podaacftp.jpl.nasa.gov/) to develop the data set. Gridded data were obtained by using the weighted average method based on Kutsuwada (1998), where the weighted average is applied to raw data within a radius of influence (300 km for zonal, 150 km for meridional direction and 36 h of time). This data set consists of gridded data with 1 × 1 degree resolution in the area covering 30°E-390°E and 60°N-80°S for daily and monthly observations from August 1, 1999to October 31, 2009.…”

“…The merged SSH data from multiple satellites have been constructed every 7 days since 1993 with horizontal resolution of 0.25°. The daily mean surface wind stress data based on QuikSCAT satellite observations since July 1999 are gridded at 0.5°horizontal resolution as part of the J-OFURO product (Kutsuwada 1998;Kubota et al 2002). Monthly climatologies are constructed for SSH and wind stress for their respective available periods.…”

Seasonal variations of the Hawaiian Lee Countercurrent induced by the meridional migration of the trade winds

et al. 2010

Seasonal variations of the Hawaiian Lee Countercurrent (HLCC) are investigated using satellite observations of sea surface height and wind stress as well as eddyresolving ocean model simulations. The HLCC is strong from summer to winter and weak in spring between the dateline and the Hawaiian Islands. In response to the seasonal migration of the northeast trade winds in the meridional direction, the wind curl dipole lee of Hawaii varies in strength, exciting westward-propagating Rossby waves. The analyses of both observations and simulations show that the propagation of Rossby waves south of the HLCC, driven by the southern pole of the wind curl dipole in the lee of the islands, contributes the most to the seasonal variations of the HLCC. Unlike the wind-driven seasonal variations, our analysis suggests that other mechanisms such as mode water intrusion or air-sea interaction may cause the interannual variations of the HLCC.
