Study of the maximum wind speeds and meteorological characteristics in Paraguay in order to differentiate synoptic and non-synoptic events, for a future update of the NP-196.

Resumo

The Paraguayan standard NP-196 Acción del Viento en las Construcciones, estimates wind action on
structures taking into consideration only synoptic events and does not account the effects of thunderstorms (TS).
Nonetheless, severe storms usually have higher values of the wind speeds than synoptic events in the region.
Currently, the adoption of a vertical profile of wind speeds for TS events is being studied internationally in order
to be included in several wind standards. Therefore, there is an urgent need to statistically study these events in
order to consider the loads of the TS and EPS winds over structures. The present work aims to classify synoptic
(EPS) and non-synoptic winds (TS) of three Paraguayan meteorological stations, looking forward to a future
update of the basic wind speeds of the NP-196.
