Recently, several changes have been observed in the Earth’s environment. This is also applicable to ocean The concept of weather routing has applied for ship navigation a long time. Many service providers offer with availability high-quality satellite data. Unfortunately, not much information available public domain as how recent change pattern affected navigation. purpose this paper fill gap. ...

Abstract. This study compares trends in the Hadley cell (HC) strength using different metrics applied to ECMWF ERA5 and ERA-Interim reanalyses for period 1979–2018. The HC is commonly evaluated by derived from mass-weighted zonal-mean stream function isobaric coordinates. Other include upper tropospheric velocity potential, vertical mid-troposphere, water vapour transport lower troposphere. Sev...

This study aims to assess the performance of European Center for Medium-Range Weather Forecasting (ECMWF) Reanalysis fifth generation (ERA5) in terms progress made over its predecessor, ERA-Interim, East Africa (EA) reproducing observed rainfall. The rainfall used as reference are Global Precipitation Climatology (GPCC) and Climate Research Unit Time Series (CRU-TS). ERA5 predecessor is evaluat...

Abstract Using the European Centre for Medium-Range Weather Forecasts (ECMWF) interim reanalysis (ERA-Interim) dataset and Specified Chemistry Whole Atmosphere Community Climate Model (WACCM-SC), impacts of sea ice reduction in Barents–Kara Seas (BKS) on East Asian trough (EAT) late winter are investigated. Results from both data simulations show that BKS leads to a deepened EAT winter, especia...

Abstract We present the first Antarctic-wide analysis of extreme near-surface air temperatures based on data collected up to end 2019 as part synoptic meteorological observing programs. consider at 17 stations Antarctic continent and nearby sub-Antarctic islands. examine frequency distributions highest lowest individual observed. The variability trends in number were examined via mean daily com...

In this article, we examine atmospheric and river discharge conditions within the Hudson Bay Complex for BaySys 2016–2018 field program time frame. Investigated in particular is a subset of European Centre Medium-Range Weather Forecasts (ECMWF) Re-Analysis - Interim (ERA-Interim) forcing variables, namely 2-m surface temperature, 10-m winds, precipitation, sea-level pressure, addition to discha...

Three-dimensional radar reflectivity fields from a dual-wavelength Doppler polarimetric radar (S-PolKa) deployed in the equatorial IndianOcean are used to evaluate the composition of the population of convective cloud elements during active phases of the MJO. Rainfall in active periods was intermittent, occurring in 11 episodes of about 2–4 days, separated by several nonrainy days. Data for the...

A first validation of water vapour total column amounts derived from measurements of the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY) in the visible spectral region has been performed. For this purpose, SCIAMACHY water vapour data have been determined for the year 2003 using an extended version of the Differential Optical Absorption Spectroscopy (DOAS) metho...

Equatorial planetary scale wave modes such as Kelvin waves or Rossby-gravity waves are excited by convective processes in the troposphere. In this paper an analysis for these and other equatorial wave modes is carried out with special focus on the stratosphere using temperature data from the SABER satellite instrument as well as ECMWF temperatures. Space-time spectra of symmetric and antisymmet...
