Schermo solare aspirato Apogee TS-100

apogee TS100 3E' ormai un anno che il KWOS ha ricevuto dalla ditta Apogee lo schermo solare TS-100. Si tratta di un rivoluzionario schermo a apogee TS100 1ventilazione forzata aspirata.

A differenza degli altri schermi aspirati, ha una camera di aspirazione molto ridotta e grazie alle sue proprietà, permette di utilizzare la ventola a bassi regimi beneficiando della possibilità di gestire la velocità con il sistema PWM (lo stesso utilizzato sui moderni PC).

La novità consiste in un ingresso dell'aria concavo tendente verso il centro. In questo modo, sfruttando l'effetto Coandă, il flusso dell'aria entra verso il centro, seguendo la superficie liscia e concava, aumentando anche la velocità con l'effetto Venturi. L'aria, così letteralmente risucchiata verso il sensore, permette di avere una ventola che gira più lentamente, che consuma meno e che tende meno a rompersi.

All about satellites

Meteosat

There are two generations of active Meteosat satellites, Meteosat First Generation (MFG) and Meteosat Second

Generation (MSG), providing images of the full Earth disc, and data for weather forecasts.

Today, weather satellites scan the whole Earth, meaning not a single tropical storm or severe weather system goes undetected. The early detection and warnings they provide have saved thousands of lives.

Meteosat data is of unique value to nowcasting of high impact weather in support of safety of life and property.

It has been shown to improve weather forecasts and severe weather warnings which, in turn helps limit damage to property and benefits industry e.g. transport, agriculture and energy.

All about lightning

Scarica (solo in italiano):
Studio sull'LPLWS NASA

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.
