Skew T diagrams For an explanation of how to read this please do some homework and read Skew T Basics on https://www.meted.ucar.edu. You need to Join which is free, then look in the turorials under convective weather or Mountain Meterology Briefing at 10.30am(need to discuss trackers use, airspace to the E, SW convergence and some general […]
Situation. High pressure dominates the peninsula with higher temperatures than yesterday. The winds are light and on PN and above the convection layer are more westerly, but at our flying levels move around from NNW to NNE but are very light. There is an inversion at 2700m early afternoon which should break leaving us another […]
Situation High pressure at surface and above the convection layer. Spreading of the isobars and hopefully less wind than yesterday, though picking up to around 20km/hr later afternoon. A slow start and slightly higher trigger temperature than yesterday so likely to be a later start. A similar route to yesterday, hand hopefully we can get […]
Situation The upper level trough has moved through leaving high pressure at lower levels and a N to NE flow in the convective layer. around 15km/hr at take off level and 30km/hr at 3000m. A marked inversion at 2600m. Probable climbs later in the afternoon to c3000m. A reasonable XC day flying towards Barco/Plasencia […]
Situation Post cold frontal with relative low pressure in the Peninsula a ground level.Relatively high windspeed and thermal tops probably not more than 27oo in our valley, though potential to over 3000m (inversion around 3.1). Scattered Cirrus throughout the day. Cross on take off at 9am and not over strong. I hope it will come […]
Weather Heat low formed over the Peninsula with a cold front out to the west. Winds a little stronger from the SW than yesterday, but reasonable and around 20km/hr but perhaps 40km/hr if we climb well above the inversion at 3200m and reach 4000m (potential if ground temp at 35ºC). Trigger temp at 28ºC which […]
A cooler day with the wind finally coming around to the PN take off. This morning at 9am light W, though we can expect possibly even NE by the afternoon. Inversions at 2600 m and c3100m. Not really getting going untill around 2pm. At 10.30am the wind is still cross over the back […]
A weak cold front going through which is considerably weakened by the high pressure at surface level. 25-30km/hr at 1500m, 65-85km/hr at 3000m. Tomorrow, and feasibly late this evening the winds should lighten and move more to the N. No attempt at flying this morning, but we will keep watch to see if we can […]
Another difficult day, more so than yesterday which had forecast winds at 20km/hr at flying levels and our main worry was the launch wind speed. Today the wind near 3000m is near 45 knots. It is very unlikely to be safe to fly. There is a heat wave coming up from Africa which often gives […]
