Abstrakt

This paper provides an overview of wind observations in Romania with historical data, particularly after the establishment of the national meteorological network in 1884. Data on wind directions and velocities is presented, focusing on a sample of fourteen cities including the capital Bucharest. The historical evolution of national zonation maps for wind pressure is shown. A statistical description of the maximum annual wind velocity data is also presented.

Keywords: wind direction, wind velocity, wind pressure map, wind code, meteorological station

Streszczenie
Atrykuł przedstawia zbiór danych z obserwacji wiatru w Rumunii wraz z zapisami z poprzedniego stulecia, dokładnie zbieranymi od momentu ustanowienia krajowej sieci meteorologicznej w 1884 roku. Przedstawiono dane dotyczące kierunków i prędkości wiatru. Skupiono się na próbie czternastu miast, w tym stolicy – Bukaresztu. Pokazano historyczną ewolucję map krajowych stref obciążenia wiatrem. Przedstawiono również statystyczny opis danych dotyczących maksymalnej rocznej prędkości wiatru.

Słowa kluczowe: kierunek wiatru, prędkość wiatru, mapa ciśnienia wiatru, norma wiatrowa, stacja meteorologiczna
