Maršruto orų modelis

Autorius: Tauras -
Dėl mūsų maršruto pasirinkimo.

Visi orų prognozės modeliai 2 mėnesius rodo, kad parankiausias 2-sis maršrutas - t.y. nuo Honolulu plaukiam į pietus , kertam pusiaują ir tuomet judam į vakarus. Priklausomai nuo perėjimo zonos, nežymiai skiriasi rekomenduojama pusiaujo kirtimo vieta, bet nei karto modelis nepasiūlė maršruto nr 1.

Ne buriuotojams trumpai paaiškinsiu pasatinių orų modelį. Virš pusiaujo šiaurinėje dalyje vėjas pučia iš rytų, su nedideliu pokrypiu iš šiaurės. Pietinėje dalyje taip pat pučia iš rytų su nedideliu pokrypiu iš pietų. maždaug ties pusiauju yra perėjimo zona, kur vėjas pučia į viršų - kas reiškia, kad ant vandens jo beveik nėra ir netvarkingas, su dideliais ir neprognozuojamais debesimis. Jei pasatinės juostos labai stabilios iš esmės visus metus, tai perėjimo zona nuolatos kinta. Nuolatos kinta zonos plotis ir forma. Jos kirtimas ir yra pagrindinis iššūkis kertant pusiaują, nes reiškia daug motoravimo dideliame karštyje ir be vėjo.

Paveikslėlyje žemiau gerai matosi šiaurės ir pietų pasatai, bei perėjimo zona kur daug silpno vėjo rodyklių be krypties. Koncentriniai ratai techninis modelio skaičiavimas ieškant greičiausio maršruto.



Nepaisant to , kad maršrute matome 14 parų gryno plaukimo, gera žinia ta, kad beveik nebus priešvėjinių kursų (surface wind angle). Bloga žinia, kad poilsiui inkaruotėse turėsime tik 3 paras norint saugiai suspėti.

Tropical South Pacific weather resources Rory Garland, S/Y Streetcar March 2014 For those cruising the tropical south Pacific and trying to make decisions based on the weather, the  number of different weather and climate resources available can seem daunting. I hope these notes  will help make some sense of it all. I’ve spent the last 2 years in the region (including two cyclone seasons) and have had the  opportunity to consider most sources of information. In the end, for me, it is the diversity of weather  information that helps make better decisions. I try to make sure I choose and compare information  from across the field of uncertainty. In this way I can get an idea of the likelihood of a forecast being  correct. It is human nature to want to know exactly what will happen, and dockside chatter is commonly  about people pinning their colours to a particular scenario. But it is worth remembering that nothing  is as ...

Kiribati formalumai

Autorius: Tauras -
Kiribati - Formalities Clearance No other island must be visited before clearing in or after clearing out. Call the appropriate port Radio on VHF 16 on arrival in Kiribati waters (Tarawa Radio, Christmas Radio, Fanning Radio or Kanton Radio). It will be necessary to collect the officials in your own dinghy. A cruising permit should be obtained when clearing in. You must report to the local police on any island you visit after clearing in to the country; some atolls have a Quarantine officer who may wish to inspect the yacht. To visit other islands during your stay in Kiribati you will need to write a letter to Principal Immigration Officer requesting permission - at least 3 days prior to intended departure. You will also need to clear with Customs to visit other islands. They will provide you with a letter of introduction to give to the local police on arrival, who will want to see your permit letter and crew passports. Permission to visit one of the outer islands is gr...
