Tenmon Era
is the ninja art of understanding and using meteorology as a strategic weapon. It allowed ninja to foresee weather changes and to use them as an advantage. By knowing nature's changes, animal behaviour, or atmospheric/astronomic signs, one could use rainy weather or a hot sunny period as strategic elements to weaken and defeat the enemy.

Ninja
A or was a covert agent or mercenary in feudal Japan. The functions of a ninja included reconnaissance, espionage, infiltration, deception, ambush, bodyguarding and their fighting skills in martial arts, including ninjutsu.Kawakami, pp. 21–22 Their covert methods of waging irregular warfare were deemed dishonorable and beneath the honor of the samurai. Though ''shinobi'' proper, as specially trained spies and mercenaries, appeared in the 15th century during the Sengoku period, antecedents may have existed as early as the 12th century. In the unrest of the Sengoku period, mercenaries and spies for hire became active in Iga Province and the adjacent area around the village of Kōga. It is from these areas that much of the knowledge regarding the ninja is drawn. Following the unification of Japan under the Tokugawa shogunate in the 17th century, the ninja faded into obscurity. A number of ''shinobi'' manuals, often based on Chinese military philosophy, were written i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteorology
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It was not until after the elucidation of the laws of physics, and more particularly in the latter half of the 20th century the development of the computer (allowing for the automated solution of a great many modelling equations) that significant breakthroughs in weather forecasting were achieved. An important branch of weather forecasting is marine weather forecasting as it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water.
