Tecnofil s.a.
Extremely strong “El Niño” rainfall periods occurrs:• Only if the SIDC curve is on RED • On the down leg of the SIDC curve when:
– coronal plasma ropes are more frequent.– rainfall storms rises the Ionosphere. (Goddard/NASA, G. Tisnado
1997.__2006)– Ionosphere feeds more heavy O+ ions into the magnetosphere

GEOMAGNETIC INFLUENCES (AE) ON HYDROMETEOROLOGY (RIVER FLOW)

SELF EVIDENT SUNGLINT over The PACIFIC
GOES WEST IMAGE, near NOON ON 28JUL2006.
Notice the sharp Sunglint, just at the ITCZ produce N_S Boundaries
Notice also a dropbit line (at the bottom), due Injection phase of a big Magnetospheric SUBSTORM
HAWAII SOUTH CLOSE-UP of 28 JULY SUNGLINT
NOTICE SUNGLINT (SG) ACTIONS:• Reconforming activity of EUV on clouds just South of SG.• Sharp boundary N_S Virtual Line (high and low tones),
just East of the visible SG.• Sharp E_W high cloud lines framing a rectangular void
[HERE UP]
REMOTE SENSING VISUALIZATION TECHNIQUES
• Notice some small EUV patches off Baja Calif. And a big arch around the natural Sunglint, in YELLOW
• GREEN indicates its boundaries
SOHO EXACTLY at 00:00UT ON 28 JULY 2006
NOTICE• Sun’s main
activity at the disk´s very center.
• N-S, E-W, 45° flare lines
• A secondary squared block S_W.
• A coronal Hole in between the two, in a dipole like configuration
FLIPPED CLOSE-UP SOHO EIT171, 28JULY2006
NOTICE ITS SIMILARITY TO THE GOES IMAGE INCLUDING:• E_W Ttraces little South of the Sun’s Equatorial Plane.• N_S line of evenly spaced clouds, just East of the center.• Squarely frames in the intermediate scale size

CLOUD EROSION
• August 28 2006
• Case Study
EFFECT OF SUNGLINT EUV RADIATION ON THE ITCZ AND PERU STRATUS, 07AUG2006 CS
SOLVING A BRAINTEASER: ¿ WHY STRATUS OFF PIURA ARE SQUARELY ?
• SOLUTION:• Because of the
eroding effect of the squarely solar flashes.
• So straight cloud-lines off PERU, are also influenced by such flashes
