Hi All, Convection confuses me. In the next few days we're forecast to have an LP sat bang over us. In the summer (especially if it was a warm LP which I know this one's not) I'm pretty certain we would be more or less guaranteed slow moving heavy - possibly thundery - showers more or less anywhere in the country. At this time of year, because the sun is less strong, this seems to be less likely - I keep looking at the LP that will be over us and having to remind myself that convection is less likely to happen - but is that true? This is where my question lies; how does the difference between a cold LP (like the PV that will be over us soon) and a warm LP (for example a Spanish Plume in August) affect convection and do we know where convection is more likely to occur in a cold and warm LP? What other factors (leaving out the effect of the sun) can contribute to convective showers being generated? TIA DS
