Meteorological phenomena are observable weather events which illuminate and are explained by the science of meteorology.
Early in the 20th century, theoretical studies of atmospheric phenomena usually were performed analytically, that is by taking the fluid-dynamical equations that govern atmosperic flow, simplifying them by neglecting lesser terms, and looking for solutions to these equations.
Meteorological instrumentation that is used at the surface or in airplanes also has room for improvement.

Temperature at Sea-Level.The temperature of the air at the surfaces of the earth and ocean and throughout the atmosphere is the fundamental element of dynamic meteorology.
The pressure is supposed to interest the engineer and navigator, but the velocity is the fundamental meteorological datum; in fact, the pressure of the wind varies with the nature of the obstacle, the method of exposure, the density of the air, and even the mass of rain carried along with it.
Electrical A pparatus.The electrical phenomena of the atmosphere undoubtedly belong to meteorology, and yet the methods of observation have been so unsatisfactory and the difficulty of interpreting the results has been so baffling that regular observations in electricity are only carried out at a very few meteorological institutions.

Early in the 20th century, theoretical studies of atmospheric phenomena usually were performed analytically, that is by taking the fluid-dynamical equations that govern atmospheric flow, simplifying them by neglecting lesser terms, and looking for solutions to these equations.
For example, Vilhelm Bjerknes developed the model that explains the generation, intensification and ultimate decay (the life cycle) of midlatitude cyclones, introducing the idea of fronts, that is, sharply defined boundaries between air masses.
In light of the decrease in density of surface and rawinsonde observations, new algorithms have to be developed to extract similarly accurate information from satellite data, for example about cloud type and distribution.

Meteorological phenomena can be forecasted, but within certain limits of which we need to be aware.
This is one of the chief lessons drawn from the meteorological events of 1999 by Météo-France and its supervising authorities.
But the limits of predictability teach us that there will always be phenomena that slip through the net of the meteorological services, even though we are actively working to reduce their number by advances in observation, modelisation and forecasting.

The result was the establishment of numerous small meteorological observatories scattered throughout the country that became local centers of scientific observation and contributed toward the development of the science.
Although designed primarily for the meteorological observers reporting to the Smithsonian Institution, the tables obtained a much wider circulation and were extensively used by a large number of meteorologists and physicists in Europe and the United States.
The reestablishment of the meteorological observations interrupted by the civil war was somewhat impeded by the fire that occurred in 1865 destroying very many of the records and instruments.

It was centered more on predicting the weather by interpreting established celestial phenomena, such as a halo around the moon, without bothering with explanations.
Other technological advances that are usually thought of mainly as part of the progression of physics were Robert Boyle's investigation of the dependence of gas volume on pressure which lead to thermodynamics and Benjamin Franklin's kite experiments with lightning.
The inputs to the mapping process are: measured wind data and topography, and possibly other meteorological data which might relate to seasonal variation, pressure, and humidity.

In fact his scientific interest was about a group of natural phenomena, meteorology, geography, physics, geomagnetism and astronomy, which are connected to each other, so a wide and systematic work of observation, collection and collation of data had to be planned.
Today meteorological monitoring, because of its detailed series of information, is an essential instrument of work for people from different working areas and with different aims: from the meteorological service manager to the civil safety engineer, from the scientist to the historian.
These data, which are useful for the study of the development of cyclones and anticyclones, responsable of meteorological phenomena changes, are mathematically elaborated with the physic laws of thermodynamics and mechanics of fluids that air, being a fluid, respects.

 Royal Meteorological Society - History 2000
According to the minutes of the meeting, they gathered "to form a society the objects of which should be the advancement and extension of meteorological science by determining the laws of climate and of meteorological phenomena in general".
It became The Meteorological Society in 1866, when it was incorporated by Royal Charter, and the Royal Meteorological Society in 1883, when Her Majesty Queen Victoria granted the privilege of adding `Royal' to the title.
To try to test this, a wide range of such meteorological variables as pressure, temperature, rainfall, and storm frequency was studied during the latter part of the nineteenth century, and claims made for the discovery of a variety of correlations between these variables and the solar cycle.

 Nat' Academies Press, Environmental Science in the Coastal Zone: Issues for Further Research (1994)
Coastal meteorology is the study of meteorological phenomena in the coastal zone caused, or significantly affected, by the sharp changes that occur between land and sea in surface transfer or elevation.
Examples of coastal meteorological phenomena include the sea breeze, sea-breeze-related thunderstorms, coastal fronts, marine stratus, fog and haze, enhanced winter snow storms, and strong winds associated with coastal orography.
Phenomena that appear similar to flow separation in classical fluid dynamics also occur in the lee of capes and other coastline salients.

From a meteorological stand point we firmly believe that there were several factors that contributed to the phenomenon which occurred yesterday.
It also refers to small scale meteorological phenomena with life spans of less than a few minutes that affect very small areas and are strongly influenced by local conditions of temperature and terrain.
Smaller phenomena are classified as micro scale while larger are classified as synoptic-scale.

This facility is largely lacking in photographing meteorological subjects with colour emulsions, where colour casts are generally undesirable, although some contrast control may be obtained in certain parts of the sky through the use of a polarizing filter.
The majority of meteorological phenomena may be regarded as lying at infinity, and it is not generally necessary to restrict the depth of field.
It is a common fallacy that because the majority of clouds and meteorological phenomena may be regarded as lying at infinity, camera shake is less of a problem than with close-up photographs because image motion is extremely small.

 Skymath National Weather Report Module
This is an overview of a unit in which students produce a national weather report and a report on their understanding of the phenomena under study.
In this investigation, students will start to examine the relationship between the different phenomena -- first temperature and wind velocity (with the development of the concept of "wind chill"), then with atmospheric pressure (with the development of regions of high and low pressure, fronts, and accompanying changes in weather patterns).
Understanding the temperature scale and the phenomena of water condensing out of the atmosphere to form clouds (change of state),studying the relationship between pressure and temperature in a gas, and relating the changing seasons to the motion of the earth, are examples.

 Forum 2004 - Documents: Managing increased weather disasters   (Site not responding. Last check: 2007-10-26)
In terms of socioeconomic and environmental factors, meteorological phenomena are becoming increasingly extreme and are producing profound crises in both underdeveloped and advanced countries.
Once the management of climatic disasters is regarded as a global phenomenon it becomes necessary for both public and private meteorological services to work in concert, as events in one location may then occur in another; this is why joint work and collaboration are indispensable.
For instance, the phenomena known as El Niño and La Niña (produced in the Pacific), which have led to climate change, are both closely linked to global warming.

 Observations of Sea Breezes by Radar
The conclusions drawn by Atlas are, at their fundamental level, based upon the meteorological fact that the onset of a sea breeze results in an air mass boundary across which there is an increase of vapor pressure and a decrease of temperature.
In cases where insects respond to meteorological conditions and thus are not valid tracers of air motion, their response intensifies, rather than reduces the observed echo.
That is, the meteorological phenomena which lead to increased reflectivity due to congregation of a large number of insects also often lead to large gradients in refractive index.

 Bryn Mawr Classical Review 2004.03.34
This is logically followed by the analysis of possibly more advanced employment of the science: while the poets are known for their deployment of various phenomena to either illustrative or metaphorical ends, the philosophers repeatedly employ meteorology to corroborate their cosmological views.
The last chapter discusses the notion of various meteorological events as it emerges in the account of one of the more encyclopedic, if not particularly creative, intellects of antiquity: Pliny the Elder, who paid for his excessive interest in natural catastrophes with his own life, dying of asphyxiation during Vesuvius' eruption.
Finally, there are the connotations of meteorological phenomena: the surviving brontologia leave us no doubt about the divinatory value of certain events.

 PUBLIC : 26 : Feature pg2
The reductive method abstracts from the phenomena to the singular law, form, or essence that such phenomena are held to express or make manifest.
For both these reasons, it makes sense to maintain the integrity of the phenomena which have been witnessed when coming up with an account, if, that is, the particularity of what has been witnessed is the interesting thing, and not the elucidation of a preconceived theory.
This is where the method of reduction and the method of multiple explanations show their central difference: the method of reduction moves, outside of time, from one level to a deeper or higher one, while the pluralist method connects occurrences across time.

 Royal Meteorological Society - A Brief History
The British Meteorological Society was not the first meteorological society to be formed in the United Kingdom.
Five years later, another Meteorological Society of London was founded, but this, too, was shortlived, for, in the summer of 1850, its Council dissolved the Society and recommended the members to join the British Meteorological Society.
A brief history of the Royal Meteorological Society was published by R A S Ratcliffe in Weather in July 1978 (Volume 33, pp.261-268).

 Chapter XI - From "The Prince Of The Power Of The Air" To Meteorology
This theory, which attributed injurious meteorological phenomnena mainly to the purposes of God, was a natural development, and comparatively harmless; but at a very early period there was evolved another theory, which, having been ripened into a doctrine, cost the earth dear indeed.
These peculiar phenomena, made much of by the allegorizing sermonizers of the day, were used in moral lessons from every pulpit.
Luther, while never doubting that troublesome meteorological phenomena were caused by devils, regarded with contempt the idea that the demons were so childish as to be scared by the clang of bells; his theory made them altogether too powerful to be affected by means so trivial.
