v angličtině (mimochodem já tvrdím něco podobnýho a nezávisle na tomto textu od roku 2006 a loni jsem o tom psal taky - ovšem u nás bez odezvy)

Novy1 I just came across this, there's even a recent study about it. Has anyone seen
it?

In 1925, C. T. R. Wilson proposed a mechanism by which electrical discharge
from lightning storms could propagate upwards from clouds to the ionosphere.
Around the same time, Robert Watson-Watt, working at the Radio Research Station
in Slough, UK, suggested that the ionospheric sporadic E layer (Es) appeared to
be enhanced as a result of lightning but that more work was needed. In 2005, C.
Davis and C. Johnson, working at the Rutherford Appleton Laboratory in
Oxfordshire, UK, demonstrated that the Es layer was indeed enhanced as a result
of lightning activity. Their subsequent research has focussed on the mechanism
by which this process can occur.

A následně psal Jurgen tohle:

Novy1 A few hams did that for 2m and found no connection between lightning and Es
formation. But they did not rule out that it exists, only their result did not
prove it. More research is required.

Many DXer (myself included) have observed Es signals right before a local
T-storm approached but not when it had passed thru. That speaks against all
theories of refraction at path midway, and might just be pure coincidence.
