  2. Weather station - Wikipedia

    en.wikipedia.org/wiki/Weather_station

    A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate. The measurements taken include temperature, atmospheric pressure, humidity, wind speed, wind direction, and precipitation amounts.

  3. List of Dewey Decimal classes - Wikipedia

    en.wikipedia.org/wiki/List_of_Dewey_Decimal_classes

    List of Dewey Decimal classes. The Dewey Decimal Classification (DDC) is structured around ten main classes covering the entire world of knowledge; each main class is further structured into ten hierarchical divisions, each having ten divisions of increasing specificity. [1] As a system of library classification the DDC is "arranged by ...

  4. Microclimate - Wikipedia

    en.wikipedia.org/wiki/Microclimate

    Microclimate. Microclimate on rock located in intertidal zone in Sunrise-on-Sea, South Africa. A microclimate (or micro-climate) is a local set of atmospheric conditions that differ from those in the surrounding areas, often slightly but sometimes substantially. The term may refer to areas as small as a few square meters or smaller (for example ...

  5. R-value (insulation) - Wikipedia

    en.wikipedia.org/wiki/R-value_(insulation)

    The R-value (in K ⋅ m 2/ W) is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive [2] flow of heat, in the context of construction. [3] R-value is the temperature difference per unit of heat flux needed to sustain one unit of heat flux between the ...

    Le Corbusier's Five Points of Architecture. Le Corbusier's Five Points of Architecture is an architecture manifesto conceived by architect, Le Corbusier. [1] It outlines five key principles of design that he considered to be the foundations of the modern architectural discipline, which would be expressed through much of his designs. [2]

  7. Weather - Wikipedia

    en.wikipedia.org/wiki/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 cloudy. [ 1 ] On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, [ 2 ][ 3 ] just below the stratosphere. Weather refers to day-to-day temperature ...

  8. Numerical weather prediction - Wikipedia

    en.wikipedia.org/wiki/Numerical_weather_prediction

    Weather reconnaissance aircraft, such as this WP-3D Orion, provide data that is then used in numerical weather forecasts.. The atmosphere is a fluid.As such, the idea of numerical weather prediction is to sample the state of the fluid at a given time and use the equations of fluid dynamics and thermodynamics to estimate the state of the fluid at some time in the future.

  9. Systems architecture - Wikipedia

    en.wikipedia.org/wiki/Systems_architecture

    Example of a high-level systems architecture for a computer. A system architecture is the conceptual model that defines the structure, behavior, and more views of a system. [1] An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the ...
