Interval Lunitidal? Am cam înţeles eu ce e, dar vreau să ştiu care e acest interval/durată pentru România. Ştie cineva?

Nu am avut rabdarea/curiozitatea sa calculez - mai ales ca la noi fluxul/refluxul nu prea se simte.

QuoteHow do I find the lunitidal interval?
Lunitidal interval is the difference between moon up and the high tide immediately following moon up. Moon up is when the moon is directly over the person's longitude, not when it rises. Under ideal circumstances, the high tide and moon up time would be the same. Friction and the ocean floor cause the ocean to move at a different rate in different areas. Adjusting for this difference will give you a more accurate tide reading. You may find the following Web page to be helpful for finding the lunitidal interval:
http://co-ops.nos.noaa.gov/faq2.html#22

You can also calculate lunitidal interval by going to:

http://aa.usno.navy.mil/data/docs/RS_OneYear.html

Use Form A, and change type of table to moonrise/ moonset. Select state, and enter city for the tide you want to calculate. Or find some other way to find what the latitude and longitude is and when the moonrise and moonset. Halfway between these times would be the moon up.

Next, find the tide times for that day. These are usually in most newspapers that have a coastline, a local marina, or from the following site:

The lunitidal interval is the difference from moon up until the first high tide after moon up.

During DST, the tide time may be 1 hour off. Add 1 hour to the lunitidal interval.

Mersi mult.
Acum mai am nevoie doar de ora la care a fost primul flux dintr-o zi.

Dacă e legat de maree (din câte am înţeles la o privire rapidă), vezi că în România nu avem aşa ceva. De fapt, dacă nu mă lasă memoria, nu au maree decât mările cu deschidere la ocean.
We watch and we are always here.

Da, despre maree e vorba. Flux si reflux. Am nevoie de date ca să-mi setez ceasul (Casio).
Ar fi ca cam trist sa aflu acum că marea noastră dragă şi neagră nu are aşa ceva...
Eşti sigură?

Are da' sunt mici, ca în toate mările (aproape) închise. Cel mai sigur încearcă la tipii de la Observator (ăla astronomic, nu ăla de la Antena 1/3) sau ceva căpitănie de port, ăia au tabele cu toate chestiile astea. În US există USNO care se ocupă cu toate treburile astea şi le pune la dispoziţia publicului.
Would you like to ride on your own ass?
