I marked the shadow of a pillar cast on my garden wall at sunrise this morning and am about an hour away from doing the same from a second pillar at sunset. Happy Solstice.

while I'm writing these lines right now… lingering moderate showers… lightnings… and thunder are occuring in my sky…
there was almost no sun this june solstice in my location… as convective clouds were regularly fueled by some amount of moisture both in the low and middle levels of the troposphere…
…………………..
african airmasses have been gradually making their way through the atlantic ocean trade winds for about one month… with much to some days considerable saharan sand dust amounts reducing the visibility to less than 10 kilometers… 6 miles… and making the sky loose its blue color…
all this accumulated energy above my head began to collapse since last week-end with abundant showers…
and while sunny skies and strong diurnal heating prevailed yesterday after this first rainy round... a return flow is currently certainly leading the trade winds to reorganize themselves over my area as they must have been disturbed by the last week-end african wave I've just talked about…
so… this return flow must produce a surge of moisture from the atlantic ocean… which therefore may be fanning the big cumulus to cumulonimbus clouds present in my sky since early this morning…
…………………………..
my island is between the 14th and the 15th northern parrallels…
so that the june solstice is a relative minimum in the sunlight radiations…
this day… the sun culminates in the sky by about 80 degrees of height toward the north… rising to the east-north-east and setting to the west-north-west… so non visible this 2018 year… lol…
…….
there are two maxima in the sunlight radiations in my location during a given year…
the first one has already occured… it was between april 28th and april 30th...
the second maximum is by mid-august…
during these maxima… the sun reaches the zenith point of my sky… 90 degrees of height…
ok… I wish to my northern hemisphere lpsg fellows a good summer time… and a good winter time to my southern hemisphere fellows...
