North Atlantic Oscillation - definitions, manifestations, influence on European climate
Huth, Radan
The paper reviews basic knowledge on the North Atlantic Oscillation (NAO), including its manifestations in the atmospheric pressure and geopotential height fields, definitions, methods of detection, effects on surface climate elements (temperature, precipitation) mainly in Europe, connections to phenological phases of some plant species, and relationships with solar activity.

The heat-stress-related mortality in the Czech Republic: first results
Kyselý, Jan ; Huth, Radan ; Kříž, B.
The analysis of the HSR mortality in the Czech Republic tries to find answers to the following questions: (i) which treshold value of tempereture (or of another temperature- and humidity- related variable)must be exceeded to observe the HSR mortality, in dependence on time of the year; (ii) which meteorological variable (or an index) accounts for the largest portion of the mortality increase, and what is the best model between meteorological variables and mortality; (iii) what is the dependence of the HSR mortality on the age group and sex; and (iv) whether a synoptic approach based on an objective classification of air masses leads to better results compared to the more traditional methods. The analysis covers the 1990s when some extremely hot summers appeared in the Czech Republic.
