WoW, this has been quite a hectic month where field trips are concerned. We’ve done SAASTA Telescope Building & Science Outing; Steam Train Trip & Cullinan History Tour; eTV Tour; SAASTA Night Sky Viewing as well as the Weather Training Centre in Irene. That’s 5 Field trips in one month & more than I can remember doing in all of my schooling career. Obviously in the process I’m also re-learning a whole lot of stuff that I learnt for the test many years ago but remember none of…
This afternoon we visited the Irene Weather Station, one of the 23 weather stations in our country. We met Hendrik, a technician with an absolute passion for the job he’s doing. Very patiently, & with the simplest of terms, he explained how they measure air temperature, humidity, air pressure, wind speed & direction as well as direction are measured & sent to their Head Office where the information is processed to supply the public with climate & weather reports.
I was quite surprised at how simple it all is. Now here is one area where the digital collection is still verified daily by taking daily measurements the old primitive way & checking it with the automated readings. We also had the privilege of seeing a radiosonde that measures various atmospheric parameters and transmits them to a fixed receiver, being attached to a balloon & released for a daily reading taken for the aviation industry.
Although this may not have been a very WoW experience we still enjoyed this field trip & learnt a lot.
