Metabolic syndrome (MetS) is purportedly related to risk of developing colorectal cancer; however, the association of MetS, as defined according to recent international criteria, and colorectal cancer has not been yet evaluated. In particular, it remains unclear to what extent the MetS components individually account for such an association. We addressed these issues in a nested case-control st...

W ind and temperature data from radiosondes and aircraft are main sources of in situ information to data assimilation systems for NWP (see Table 1 for acronym definitions). Currently, there are about 150,000 automated aircraft reports per day, used at the NCEP, with approximately 3 times as many temperature observations than there are from radiosondes. NCEP operational analyses use automated ai...

The land surface soil moisture is a crucial variable in weather and climate models. This study presents a land data assimilation system (LDAS) that aims to improve the simulation of the land surface soil moisture and energy fluxes bymerging themicrowave remote sensing data and the general circulationmodel (GCM)output into a land surfacemodel (LSM). This systemwas applied over the TibetanPlateau...

The stratospheric mean-meridional circulation (MMC) and eddy mixing are compared among six meteorological reanalysis data sets: NCEP-NCAR, NCEP-CFSR, ERA-40, ERA-Interim, JRA-25, and JRA-55 for the period 1979–2012. The reanalysis data sets produced using advanced systems (i.e., NCEP-CFSR, ERA-Interim, and JRA55) generally reveal a weaker MMC in the Northern Hemisphere (NH) compared with those ...

BACKGROUND How weight change affects the metabolic syndrome (MS) and its parameters is unknown, particularly, in a leaner European population such as the French prospective D.E.S.I.R. cohort. METHODS In 3770 D.E.S.I.R. participants (sex ratio=1) averaging 47.5 years (range 30-64), with measured weight and MS parameters at baseline (D0) and at 6 year follow-up (D6), we assessed this relationsh...

BACKGROUND The National Cholesterol Education Program (NCEP) has provided guidelines for identification of persons at high risk of coronary heart disease (CHD) because of lipid abnormalities. These recommendations are based on total cholesterol as the initial screening tool and have become the stimulus for clinic- and community-based screening programs nationwide. However, the use of the guidel...

Wildfires are a major concern on the Iberian Peninsula, and the establishment of effective prevention and early warning systems are crucial to reduce impacts and losses. Fire weather indices are daily indicators of fire danger based upon meteorological information. However, their application in many studies is conditioned to the availability of sufficiently large climatological time series over...

Abstract In precipitable water vapor (PWV) retrievals from Global Navigation Satellite System (GNSS) data, the two essential parameters, namely, surface pressure ( ) and weighted mean temperature ), are often not available due to lack of collocated meteorological sensors or improper data retention. Hence, this study presents a comprehensive assessment GNSS PWV retrieval using alternative Europe...
