Validation of Satellite-Only GGMs over the Western Part of North Macedonia [PDF]
Geodetski GlasnikThe purpose of this research is to identify the most suitable Global Geopotential Model (GGM) for geoid determination in a specific region of Western Macedonia. The selection of the most suitable GGM eliminates the evaluation of numerous alternatives and

An intercomparison of subtropical cut-off lows in the Southern Hemisphere using recent reanalyses: ERA-Interim, NCEP-CFRS, MERRA-2, JRA-55, and JRA-25 [PDF]
, 2020 Four recent reanalysis products ERA-Interim, NCEP-CFSR, MERRA-2 and JRA-55 are evaluated and compared to an older reanalysis JRA-25, to quantify their confidence in representing Cut-off lows (COLs) in the Southern Hemisphere.

International Journal of Climatology, EarlyView.Significant trends of precipitation totals are visible at seasonal (negative in spring and positive in winter) and monthly level. The deepening rainfall deficit in April in Western Sudetes threatens the stabilisation of forest ecosystems, the preservation of biodiversity and significantly limits water resources for economic use.

Determination of deflection of the vertical components by using global geopotential model EGM2008 [PDF]
Tehnika, 2018 This paper presents the determination of the vertical deflection components using the Global Geopotential Model EGM2008. The components are defined in two groups of points: 4083 points are relatively correctly distributed across the territory of Serbia ...

On the meridional asymmetry of the poleward‐displaced intertropical convergence zone
Quarterly Journal of the Royal Meteorological Society, EarlyView.We analyze the complex, asymmetrical dynamical structure of the intertropical convergence zone (ITCZ) in the East Pacific and Atlantic basins, seen during boreal summer, using a global, coupled storm‐resolving simulation. The equatorial pressure gradients lead to the acceleration of southerlies, which decelerate when the zonal flow becomes westerly ...

Improving Geoidal Height Estimates from Global Geopotential Model Using Regression Model and GPS Data [PDF]
, 1997 Conventionally, for most application, position of a point is often referred to the geoid as the reference surface. Thus there is an important need for the knowledge of the geoid undulation in the area where positioning tasks is performed, This ...

Mesoscale dynamics of cyclone Leslie (2018): A diagnostic analysis of a rare Iberian landfall
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study presents a successful numerical simulation of cyclone Leslie (2018), using WRF‐ARW v4.5.1. Several mesoscale dynamics were identified indicative of the occurrence of sting jet and cold conveyor belt, which potentiated the record‐breaking winds in central Portugal.
