The Black Sea Breeze - as a trigger

Visible channel (sat24.com) from EUMETSAT. The sea breeze acts like a lifting mechanism for convection initiation in Dobrudja. The general circulation in SE Romania is from South, and will produce propagation toward the South, and there is a strong low level flux of moisture from the sea to Moldova. Severe weather is expected in the Eastern half of Romania, several supercells.

Later: a supercell splits: on satellite (two red circles), and radar (zoom on the SE part of Romania). Is nice to observe the huge dimensions of the anvil.

A Mesovortex Over South of Romania

High Resolution Visible. EUMETSAT, NMA

A Bow Echo

An early morning bow echo approaching the Bucharest area. Seen on Radar (with a zoom around Bucharest). visible sat chanel (from sat24.com) and RGB-airmass product (EUMETSAT,NMA).
The dry air behind the system (west of Bucharest), is the trigger of the bow, but the rear inflow jet is high, so instead of wind, a rain-pool can form with a flash-flood.
Heavy rain is expected.

An Innocent Outflow

The arrow points a small convective cell that produces a significant outflow 30 minutes later. The cell doesn't contain rain, so the radar (OWT national mosaic) doesn't get it. This is an example on how subtle mesoscale features and sources of weather changes can be.

Undular Bores on radar and satellite

Undular Bores leaving a strong convective system.
Easier to see on visible satellite because they are too shallow for the radar horizont.
We expect severe weather today in the Western and Southwestern Romania, heavy rainfall, wind gusts.

ERAD2010 - participants

The deadline for early registrations has come.
I wonder how much this event is impacting on my life. Well, I am addicted to it.

I look everyday, several times, at the list of people who registered. People I admire so much. I know their work, I know their passion. Some of them are my favourites, my models.

Some of them are new to me but "old" in the branch, I am so glad to discover them. Some of them are students. This edition is dedicated to them, to their courage to follow a scientist career in difficult times; and to women in radar science. If I could bring closer to 50-50 the percentage in gender participation, I could say I have accomplished one target.

I am going back now to contemplate again the list of great radar scientist people that will reach and enrich ERAD. I can not work too much these months for my own life, but I know that ERAD will bring something good to many people, and this is the most important reason to do things.
