BE YOUR OWN WEATHER FORECASTER

3. • In my introducing, i want to be as brief as i can, making a short remark on my personal
motive building this site. If you notice, entire my webpage is based on many weather links
from many authorised sources in order to get you, all data and extra dates, just for create
proper weather forecast when you need.
• You also see links from unauthorised sources, but, that was main tip, just to can compare
all sources among them and, so that, you can easly reach at a proper conclusion about
synoptical weather context, and so on. Many and many weather centers, locals and
regionals, not few times, have differents points of view, in regard to a sinoptical context,
more then enough, their numerical weather products that comes from own sources, are
differents.
• I don’t want to incriminate some weather centers of prognosis, but all of us know, that air
mases are in a continuous mixing, due to uneven warming of air volumes on earth,
influencing also its dynamical processes.
• So, in order to get a weather forecast, near reality, you also need a tough, best and
complete source. I did’t want to put and assemble pictograms like other sites did, why,
because we have right now all necessary instruments, here, next to us, to make a
prognosis better then ever, and maximize abilities of self prognoser.
• You may also ask me anytime, any question regarding weather and, is compulsory to
require to add extra dates our briefing, if is necessary, making also progress in learning
process of prognosis.
• In the beginning, I intend to make a weather prognosis about 24hours/short prognosis,
along Romania seaside- Tuzla Airfiled, right now. If you consider to change the point of
prognosis, you may ask me and will keep going with the other zone, ok?
• I will gather important sinoptical maps(depending on synoptical context) in order to
make a weather forecast near to reality, but, right now i choose them at random.
REMEMBER,IGNORE IT PEREMPTORY, IS NOT AN OFFICIAL SOURCE, IS
JUST FOR TRAINING !

4. For 19.Aug.2012, if we take a glance, we
notice that synoptical context is one
favorable, I mean that LRTZ is centered
in rare of two successive cold fronts
( continuous black curves) and in front
part of that maximum barometer, so
far so good.
We easily take a conclusion about
tomorrow, that we have a good
weather , but let see further.First of all,
i must to make a specification: In
Northern Emisphere, Anticyclone has a
clockwise motion, in our case, air
movement is from North to South and
in Southern part, its direction of
motion is anticlockwise.

5. Here we have depicted a relative map,
TR500/100Hpa.Dotted lines show us
upper air advections.If we see them in
left of continuous lines, this confirms
us that we have an advection of cold
air, roughly speaking, confirm that
LRTZ was pasted by a cold front.

6. This chart, depicts a topography
absolute map with much more isolines.
Green shaded zones reveal field of
relative dampness in upper air, in this
case: TA-700Hpa(mb)= 3000m height.
If we don’t see any shaded green
spotted above our interested zone, we
will not have for tomorrow
precipitation and overcast clouds
coverage predicted.

7. This one, shows us all area of precipitation zone, as you easily see, entire zone will be
retreated along cold front, from west to east.

8. So, all blue shaded with quantity of precipitations will be registered from center zone of
Black Sea, in Eastern part of it.

9. I have talked about streams of current in previous map , which describing air motion .
There are lines of air current from NNW at 5-7mps arround 9LT(local time)

10. You notice streamlines how decrease in intensity along LRTZ and keep them directions

11. Here we are, two maps which reveal
relative humidity arround 2m
height.We know that, if we are in back
part of a cold front, we have an air
more pure and less humid than
moment of passing of it(in other cases
can pass with adjacents phenomena
and a lot of humidity).
So, early morning, relative humidity at
ground is forecasted arround 70
percentages and decrease at noon at
50-60 percentages, that is very good, it
means that horizontal visibility will be
over 10Km without any phenomena
that could reduce horizontal visibility.

12. Here we are, two maps which display
minimum and maximum temperatures.
All temperatures, as you see, are
measured in Celsius degrees.

13. Of course, if you have a ship, you can
easily make a trip with it, along
Romania seaside, just as, sea state
permitted to navigate securely.

14. Here you are, at noon, wave direction
and height, if you coastal navigate, are
approximately the same,
from North at 0,6-0,9m height.

15. In that patterns we have depicted
periodicity of waves, all are measured
in seconds. In our case we see, in
eastern part of LRTZ(Tuzla airfield),
that waves’periodicities are 3,6-4,05”.
