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.

Satellite techniques for determining the geopotential for sea-surface elevations [PDF]
Spaceborne altimetry with measurement accuracies of a few centimeters which has the potential to determine sea surface elevations necessary to compute accurate three-dimensonal geostrophic currents from traditional hydrographic observation is discussed ...

A Tropospheric Assessment of the ERA-40, NCEP, and JRA-25 Global Reanalyses in the Polar Regions [PDF]
The reliability of the global reanalyses in the polar regions is investigated. The overview stems from an April 2006 Scientific Committee on Antarctic Research (SCAR) workshop on the performance of global reanalyses in high latitudes held at the British ...

On the meridional asymmetry of the poleward‐displaced intertropical convergence zone
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 ...

The performance of GOCE-based geopotential models is assessed for the estimation of offsets for three regional vertical datums in Canada with respect to a global equipotential surface using the GNSS benchmarks from the first-order vertical control ...

Mesoscale dynamics of cyclone Leslie (2018): A diagnostic analysis of a rare Iberian landfall
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.

Height determination using GPS data, local geoid and global geopotential models [PDF]
Orthometric heights are normally derived using the spirit levelling. This requires the spirit level equipment to be set up from point 10 point along a levelling line which is a time consuming and tedious task.
