Tornado activity is associated with extreme convective weather which can cause extended damage and even in some cases the loss of life. The complex inland terrain of Greece along with the Ionian Sea a...
Reconstructing 20th century global hydrography:a contribution to the Global Terrestrial Network- Hydrology (GTN-H)
global hydrography contribution Global Terrestrial Network- Hydrology
2010/2/1
This paper presents a new reconstruction of the 20th century global hydrography using fully coupled water balance and transport model in a flexible modeling framework. The modeling framework allows a ...
Increase of upper troposphere/lower stratosphere wave baroclinicity during the second half of the 20th century
upper troposphere lower stratosphere wave baroclinicity 20th century
2009/12/31
A strengthening of the equatorward temperature gradient in the upper troposphere/lower stratosphere (UTLS), at subtropics and midlatitudes, is consistently reproduced in several modelling studies of t...
Hydrology is a geoscience, whose scientific basis lies mainly in physics, but also
in chemistry and biology of the endless cycle of water. This so called hydrological cycle
is a global geophysical p...
Some Highlights of Finnish Research in Solid Earth and Applied Geophysics in the 20th Century
Applied Geophysics Solid Earth observatories geological mapping geothermal research
2009/6/9
The development of non-seismic aspects of solid Earth geophysics in Finland is described along
five major lines: geomagnetic research at observatories, applied geophysics to assist mineral prospectin...
The Earth was considered to be a sphere until the end of the 17th century. Only
then, the concept of an Earth flattened at the poles was beginning to gain support among
scientists. A powerful influe...
