A Good Start (and a Lenticular Cloud photo)

| | Comments (0)
Yes we arrived here safe and sound. I'm sure everyone else has filled you in on what we've been up to. It is amazing how much has grown in the last 12 months. It should show up well in the panoramic photos. We have a smaller group this year but we've been making lots of progress. Natalia and myself have completed most of the panoramic photos although they need some formatting. I have also just updated the map with Nick's ant trap locations (marked with insect icons - I need to update the key when I get back), and a modified location for one bird point which we had to move due to fence/path changes.

The weather has been co-operative. Lots of rain but it is typical rainy season weather, arriving mid-afternoon. So we have some clear mornings, like the photo below of Arenal that I took this morning from our cabin.

It is quite common for strong winds across a prominent peak (eg. a volcano) to form a "cap" cloud or lenticular cloud (similar but above it), as the air is forced up, condenses, and then sinks again. Here we have the 'cap', but the hot steam from Crater D is being carried down the west (right) side of the volcano in the downdraft. Then when the downdraft stops, buoyancy takes over and we get the convection cloud on the right. And this has two lenticular clouds of its own above it!  A photograph for the meteorologists, I think!

We have also seen land slides (?active lava?) on the north east side for the first time - this was yesterday lunchtime in the grey area to the right. A large amount of rock fell and it almost reached the vegetation. This has become more common in the past year and many people think activity will switch to this side soon.
