Basic Meteorology for an Observing/Astrophotography Night

Presenter(s): Peter Matters

Affiliation(s): ASV

Session details: Saturday, 2022-04-23 04:15:00, ONL

Abstract

I will start by discussing how temperature and dew point/relative humidity are related and work together. This will be explained using the examples of the kitchen kettle and the bathroom shower/mirror, and how they are related to cloud formation. Next will be the interpretation of BoM rain forecasts followed by an explanation of synoptic charts and what they indicate. A basic explanation of Highs, Lows, and Cold Fronts will round off this section. Satellite photos (visual and infrared) will be next, showing the correlation with synoptic charts. The talk will conclude with making a forecast using BoM forecasts, synoptic charts, satellite photos, sky visuals, and gut feel – followed by questions if time permits.

Biography

I have been an amateur meteorologist/storm chaser for many years – not to mention a keen interest in astrophotography (getting out there on the scope doing long exposures.) I have also taken many weather pictures including lightning, as well as recording thunder in its full dynamics. My passions for weather and astronomy since my childhood inspired me to do this presentation which I have previously delivered several times to different sections of the ASV.
