Weather Forecast
Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time. People have attempted to predict the weather informally for millennia and formally since the 19th century. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere, land, and ocean and using meteorology to project how the atmosphere will change at a given place. Once calculated manually based mainly upon changes in barometric pressure, current weather conditions, and sky condition or cloud cover, weather forecasting now relies on computer-based models that take many atmospheric factors into account. Human input is still required to pick the best possible forecast model to base the forecast upon, which involves pattern recognition skills, teleconnections, knowledge of model performance, and knowledge of model biases. The inaccuracy of forecasting is due to the chaotic nature of the atmosphere, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Francis Beaufort
Rear-Admiral Sir Francis Beaufort (; 27 May 1774 – 17 December 1857) was an Irish hydrographer, rear admiral of the Royal Navy, and creator of the Beaufort cipher and the Beaufort scale. Early life Francis Beaufort was descended from French Protestant Huguenots, who fled the French Wars of Religion in the sixteenth century. His parents moved to Ireland from London. His father, Daniel Augustus Beaufort, was a Protestant clergyman from Navan, County Meath, Ireland, and a member of the learned Royal Irish Academy. His mother Mary was the daughter and co-heiress of William Waller, of Allenstown House. Francis was born in Navan on 27 May 1774. He had an older brother, William Louis Beaufort and three sisters, Frances, Harriet, and Louisa. His father created and published a new map of Ireland in 1792.

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the World War II, Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority ...

Windward And Leeward
Windward () and leeward () are terms used to describe the direction of the wind. Windward is ''upwind'' from the point of reference, i.e. towards the direction from which the wind is coming; leeward is ''downwind'' from the point of reference, i.e. along the direction towards which the wind is going. The side of a ship that is towards the leeward is its "lee side". If the vessel is heeling under the pressure of crosswind, the lee side will be the "lower side". During the Age of Sail, the term ''weather'' was used as a synonym for ''windward'' in some contexts, as in the '' weather gage''. Because it captures rain, the windward side of a mountain tends to be wet compared to the leeward it blocks. Origin The term "lee" comes from the middle-low German word // meaning "where the sea is not exposed to the wind" or "mild". The terms Luv and Lee (engl. Windward and Leeward) have been in use since the 17th century. Usage Windward and leeward directions (and the points ...

Electrical Telegraph
Electrical telegraphs were point-to-point text messaging systems, primarily used from the 1840s until the late 20th century. It was the first electrical telecommunications system and the most widely used of a number of early messaging systems called '' telegraphs'', that were devised to communicate text messages quicker than physical transportation. Electrical telegraphy can be considered to be the first example of electrical engineering. Text telegraphy consisted of two or more geographically separated stations, called telegraph offices. The offices were connected by wires, usually supported overhead on utility poles. Many different electrical telegraph systems were invented, but the ones that became widespread fit into two broad categories. The first category consists of needle telegraphs in which a needle pointer is made to move electromagnetically with an electric current sent down the telegraph line. Early systems used multiple needles requiring multiple wires. The f ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Weather Lore
Weather lore is the body of informal folklore related to the prediction of the weather and its greater meaning. Much like regular folklore, weather lore is passed down through speech and writing from normal people without the use of external measuring instruments. The origin of weather lore can be dated back to primeval men and their usage of star studying in navigation. However, more recently during the Late Middle Ages, the works of two Greek philosopher-poets, Theophrastus of Eresus on Lesbos and Aratus of Macedonia, are known for shaping the prediction of weather. Theophrastus and Aratus collated their works in two main collections for weather lore: ''On Weather Signs'' and ''On Winds.'' These were used for helping farmers with harvest, merchants for trade and determining the weather the next day. Astrology and weather lore have been closely interlinked for many years - with each planet often being associated with a weather state. For example, Mars is red and must therefore ...

Lunar Phase
Concerning the lunar month of ~29.53 days as viewed from Earth, the lunar phase or Moon phase is the shape of the Moon's directly sunlit portion, which can be expressed quantitatively using areas or angles, or described qualitatively using the terminology of the 4 major phases: new moon, first quarter, full moon, last quarter and 4 minor phases: waxing crescent, waxing gibbous, waning gibbous, and waning crescent. The lunar phases gradually change over a synodic month (~29.53 days) as the Moon's orbital positions around Earth and Earth around the Sun shift. The visible side of the Moon is variously sunlit, depending on the position of the Moon in its orbit. Thus, this face's sunlit portion can vary from 0% (at new moon) to 100% (at full moon). Each of the 4 major lunar phases (see below) is ~7.4 days, with +/− 19 hours in variation (6.58–8.24 days) due to the elliptical shape of the Moon's orbit. Phases of the Moon There are four ''principal'' (primary/major) lunar phases ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Aramaic
The Aramaic languages, short Aramaic ( syc, ܐܪܡܝܐ, Arāmāyā; oar, 𐤀𐤓𐤌𐤉𐤀; arc, 𐡀𐡓𐡌𐡉𐡀; tmr, אֲרָמִית), are a language family containing many varieties (languages and dialects) that originated in the ancient region of Syria. For over three thousand years, It is a sub-group of the Semitic languages. Aramaic varieties served as a language of public life and administration of ancient kingdoms and empires and also as a language of divine worship and religious study. Several modern varieties, namely the Neo-Aramaic languages, are still spoken in the present-day. The Aramaic languages belong to the Northwest group of the Semitic language family, which also includes the Canaanite languages such as Hebrew, Edomite, Moabite, and Phoenician, as well as Amorite and Ugaritic. Aramaic languages are written in the Aramaic alphabet, a descendant of the Phoenician alphabet, and the most prominent alphabet variant is the Syriac alphab ...

Nabatean Agriculture
''The Nabataean Agriculture'' (), also written ''The Nabatean Agriculture'', is a 10th-century text on agronomy by Ibn Wahshiyya (died ), from Qussīn in present-day Iraq. It contains information on plants and agriculture, as well as on magic and astrology. It was frequently cited by later Arabic writers on these topics. ''The Nabataean Agriculture'' was the first book written in Arabic about agriculture, and the most influential. Ibn Wahshiyya claimed that he translated it from a 20,000-year-old Mesopotamian text. Though some doubts remain, modern scholars believe that the work may be translated from a Syriac original of the 5th or 6th century AD. In any case, it is clear that the work is ultimately based on Greek and Latin agricultural writings, heavily supplemented with local material. The work consists of some 1500 manuscript pages, principally concerned with agriculture but also containing lengthy digressions on religion, philosophy, magic, astrology, and folklore. Some of ...
