Welcome to KWOS website

The phenomenon of lightning is actively investigated since 1752, when the American statesman and scientist B.Franklin one of the first established the electrical nature of lightning. As a whole the picture of formation of lightning is as follows. The terrestrial atmosphere is very good dielectric located between two conductors - a surface of the ground from below and the top layers of an atmosphere, including an ionosphere, from above. These layers are passive components of a global electric circuit. Between negatively charged surface of the ground and positively charged top atmosphere the constant potential difference of about 300.000 V is supported. According to the idea for the first time stated by Wilson in 20th years this ionosphere potential arises from thunder-storms which create global electric "battery". Lightning is a visible electric charge coming from a cloud, going to either another cloud or the earth.  Usually, thunder like the sound you are hearing accompanies lightning, especially during a thunderstorm.

Un'altra stazione meteorologica è stata installata presso la sede del KWOS: Ecowitt. Si tratta di una stazione di basso prezzo che però ha delle buone qualità ed ottimi sensori, come un all-in-one anemometro ad ultrasuoni, temperatura/umidità e radiazione solare (WS80).

A questo si possono aggiungere sensori aggiuntivi di temperatura ed umidità (WH31), un sensore di PM2.5 (WH41) ed infine, un pluviometro (WH40). 
Il tutto viene gestito da un minuscolo gateway hardware (GW1000) che raccoglie le informazioni e le invia sia sul sito Ecowitt, che su altri portali a livello internazionale come Wunderground.
