Forensic Meteorology
Forensic meteorology is meteorology, the scientific study of weather, applied to the process of reconstructing weather events for a certain time and location. This is done by acquiring and analyzing local weather reports such as surface observations, radar and satellite images, other data, and eyewitness accounts. Forensic meteorology is most often used in court cases, including insurance disputes, personal injury cases, and murder investigations. This is most often the case when weather conditions were a possible factor, as in falldowns after snow and ice, wind, flooding, after aviation and nautical accidents, etc. With increasing losses from severe weather in recent years, the demand for forensic meteorological services has also grown. In the US, many forensic meteorologists are certified by the American Meteorological Society (AMS)'s rigorous Certified Consulting Meteorologist (CCM) program. Origin of the term Conrad B. Gosset, MS (Meteor), a consulting meteorologist who worked to ...

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. Meteorological phen ...

Weather
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloud cover, cloudy. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere of Earth, atmosphere, the troposphere, just below the stratosphere. Weather refers to day-to-day temperature, precipitation, and other atmospheric conditions, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth. Weather is driven by atmospheric pressure, air pressure, temperature, and moisture differences between one place and another. These differences can occur due to the effect of Sun angle on climate, Sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations: the ...

Surface Weather Observation
Surface weather observations are the fundamental data used for safety as well as climatological reasons to forecast weather and issue warnings worldwide. They can be taken manually, by a weather observer, by computer through the use of automated weather stations, or in a hybrid scheme using weather observers to augment the otherwise automated weather station. The ICAO defines the International Standard Atmosphere (ISA), which is the model of the standard variation of pressure, temperature, density, and viscosity with altitude in the Earth's atmosphere, and is used to reduce a station pressure to sea level pressure. Airport observations can be transmitted worldwide through the use of the METAR observing code. Personal weather stations taking automated observations can transmit their data to the United States mesonet through the Citizen Weather Observer Program (CWOP), the UK Met Office through their Weather Observations Website (WOW), or internationally through the Weat ...

Weather Radar
Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.). Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the precipitation. Both types of data can be analyzed to determine the structure of storms and their potential to cause severe weather. During World War II, radar operators discovered that weather was causing echoes on their screen, masking potential enemy targets. Techniques were developed to filter them, but scientists began to study the phenomenon. Soon after the war, surplus radars were used to detect precipitation. Since then, weather radar has evolved on its own and is now used by national weather services, research departments in universities, and in television stations' weather departments. Raw images are routinely used and specialize ...

Weather Satellite
A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting (covering the entire Earth asynchronously), or geostationary (hovering over the same spot on the equator). While primarily used to detect the development and movement of storm systems and other cloud patterns, meteorological satellites can also detect other phenomena such as city lights, fires, effects of pollution, auroras, sand and dust storms, snow cover, ice mapping, boundaries of ocean currents, and energy flows. Other types of environmental information are collected using weather satellites. Weather satellite images helped in monitoring the volcanic ash cloud from Mount St. Helens and activity from other volcanoes such as Mount Etna. Smoke from fires in the western United States such as Colorado and Utah have also been monitored. El NiƱo and its effects on weather are moni ...

Insurance
Insurance is a means of protection from financial loss in which, in exchange for a fee, a party agrees to compensate another party in the event of a certain loss, damage, or injury. It is a form of risk management, primarily used to hedge against the risk of a contingent or uncertain loss. An entity which provides insurance is known as an insurer, insurance company, insurance carrier, or underwriter. A person or entity who buys insurance is known as a policyholder, while a person or entity covered under the policy is called an insured. The insurance transaction involves the policyholder assuming a guaranteed, known, and relatively small loss in the form of a payment to the insurer (a premium) in exchange for the insurer's promise to compensate the insured in the event of a covered loss. The loss may or may not be financial, but it must be reducible to financial terms. Furthermore, it usually involves something in which the insured has an insurable interest established by ...

Forensic Astronomy
Forensic astronomy is the use of astronomy, the scientific study of celestial objects, to determine the appearance of the sky at specific times in the past. This has been used, if relatively rarely, in forensic science (that is, for solving problems of relevance to the legal system) and for resolving historical problems more generally, notably issues in art history. Forensic science As a forensic science in the strict sense of the term, astronomical knowledge can help resolve certain legal questions. In one reported instance, an astronomer testified in court as an expert witness as to whether a newly built house would cast a shadow on another house. More generally, questions about the sun's or moon's placement in the sky at certain times of day or night may be legally relevant, such as for determining the date on which a photograph was made. It has for instance been reported that Abraham Lincoln once successfully defended a legal case by describing the location of the Moon on the n ...

Forensic Engineering
Forensic engineering has been defined as ''"the investigation of failures - ranging from serviceability to catastrophic - which may lead to legal activity, including both civil and criminal".'' It includes the investigation of materials, products, structures or components that fail or do not operate or function as intended, causing personal injury, damage to property or economic loss. The consequences of failure may give rise to action under either criminal or civil law including but not limited to health and safety legislation, the laws of contract and/or product liability and the laws of tort. The field also deals with retracing processes and procedures leading to accidents in operation of vehicles or machinery. Generally, the purpose of a forensic engineering investigation is to locate cause or causes of failure with a view to improve performance or life of a component, or to assist a court in determining the facts of an accident. It can also involve investigation of intellec ...

Forensic Geology
Forensic geology is the study of evidence relating to minerals, oil, petroleum, and other materials found in the Earth, used to answer questions raised by the legal system. In 1975, Ray Murray and fellow Rutgers University professor John Tedrow published ''Forensic Geology''. The main use of forensic geology as it is applied today is regarding trace evidence. By examining the soil and sediment particules to be able to link a suspect to a particular crime or a particular scene. Other uses in this field of science can include theft, fraud, locating a gravesite etc. It requires the aid of many other disciplines of science such as medicine, biology, geography, engineering and many others. More recently, in 2008, Alastair Ruffell and Jennifer McKinley, both of Queen's University Belfast, published ''Geoforensics'' a book that focuses more on the use of geomorphology and geophysics for searches. In 2010, forensic soil scientist Lorna Dawson of the James Hutton Institute co-edited ...
