The Hellenic Navy (HN) (Greek: Πολεμικό Ναυτικό, Polemikó Naftikó, abbreviated ΠΝ) is the naval force of Greece, part of the Greek Armed Forces. The modern Greek navy has its roots in the naval forces of various Aegean Islands, which fought in the Greek War of Independence. During the periods of monarchy (1833–1924 and 1936–1973) it was known as the Royal Navy (Βασιλικόν Ναυτικόν, Vasilikón Naftikón, abbreviated ΒΝ).The total displacement of all the navy's vessels is approximately 150,000 tons.The motto of the Hellenic Navy is "Μέγα το της Θαλάσσης Κράτος" from Thucydides' account of Pericles' oration on the eve of the Peloponnesian War. This has been roughly translated as "Great is the country that controls the sea". The Hellenic Navy's emblem consists of an anchor in front of a crossed Christian cross and trident, with the cross symbolizing Greek Orthodoxy, and the trident symbolizing Poseidon, the god of the sea in Greek mythology. Pericles' words are written across the top of the emblem. "The navy, as it represents a necessary weapon for Greece, should only be created for war and aim to victory."...............The Hellenic Merchant Marine refers to the Merchant Marine of Greece, engaged in commerce and transportation of goods and services universally. It consists of the merchant vessels owned by Greek civilians, flying either the Greek flag or a flag of convenience. Greece is a maritime nation by tradition, as shipping is arguably the oldest form of occupation of the Greeks and a key element of Greek economic activity since the ancient times. Nowadays, Greece has the largest merchant fleet in the world, which is the second largest contributor to the national economy after tourism and forms the backbone of world shipping. The Greek fleet flies a variety of flags, however some Greek shipowners gradually return to Greece following the changes to the legislative framework governing their operations and the improvement of infrastructure.Blogger Tips and Tricks

Typhoon Melor & Tropical storm Parma

Typhoon Melor and Tropical Storm Parma

Once a powerful Super Typhoon, Parma crossed over the northern tip of Luzon Island, the Philippines, on October 3, 2009, as a Category 1 typhoon. The storm battered the island with damaging winds and heavy rain before moving over the South China Sea, where it stalled, spinning more or less in place for about a day and a half. On October 6, the storm reversed direction and moved southeast back over Luzon. What caused this change in direction? The answer is shown in this true-color image from October 6. Powerful Super Typhoon Melor moved close enough to Parma to influence its motion.

When two cyclones approach one another, they can interact in a variety of ways. One interaction is the Fujiwara Effect, in which the two storms are drawn together and begin to circle each other. In this case, Parma was drawn towards the stronger Melor. Occasionally, the stronger storm will absorb the weaker storm, but that fate wasn’t in the forecast for Parma as of October 6. The Joint Typhoon Warning Center expected Parma to move south away from Melor and eventually track west over the South China Sea on October 8.

This image blends two satellite overpasses to show the proximity of the two storms to one another. The left half of the image, containing Tropical Storm Parma, is from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite, acquired at 10:35 a.m. Philippine time. The right half of the image was taken just under two hours later by the MODIS instrument on NASA’s Aqua satellite. The time difference causes the subtle differences in lighting from one side of the image to the other.

Parma left at least 22 people dead and damaged millions of dollars of crops and infrastructure in floods and landslides across northern Luzon as of October 6, reported Reuters. The storm is likely to do more damage as it tracks slowly south over the island, pouring heavy rain. The Joint Typhoon Warning Center expected Melor to come ashore over Japan early on October 8 (local time) as a weak Category 1 typhoon.

At the time of these satellite overpasses, Tropical Storm Parma had sustained winds of about 100 kilometers per hour (60 miles per hour or 55 knots), according to the Joint Typhoon Warning Center. The storm maintains a spiral shape, but no longer has the tightly packed bands of clouds exhibited by the much stronger Typhoon Melor. At 12:10 p.m. Philippine time, Melor had sustained winds of about 200 km/hr (130 mph or 115 knots), making it a Category 4 typhoon.
