  2. Surface weather analysis - Wikipedia

    en.wikipedia.org/wiki/Surface_weather_analysis

    A surface weather analysis for the United States on October 21, 2006. By that time, Tropical Storm Paul was active (Paul later became a hurricane). Surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations.

  3. Prognostic chart - Wikipedia

    en.wikipedia.org/wiki/Prognostic_chart

    Surface weather prognostic charts for mariners indicate the positions of high and low pressure areas, as well as frontal zones, up to five days into the future. Surface wind direction and speed is also forecast on this type of chart. Wave prognostic charts show the expected sea state at some future time. [2]

  4. Trend surface analysis - Wikipedia

    en.wikipedia.org/wiki/Trend_surface_analysis

    Trend surface analysis is a mathematical technique used in environmental sciences (archeology, geology, soil science, etc.). Trend surface analysis (also called trend surface mapping) is a method based on low-order polynomials of spatial coordinates for estimating a regular grid of points from scattered observations.

  5. Secondary ion mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Secondary_ion_mass...

    Static SIMS is the process involved in surface atomic monolayer analysis, or surface molecular analysis, usually with a pulsed ion beam and a time of flight mass spectrometer, while dynamic SIMS is the process involved in bulk analysis, closely related to the sputtering process, using a DC primary ion beam and a magnetic sector or quadrupole ...

  6. History of surface weather analysis - Wikipedia

    en.wikipedia.org/wiki/History_of_surface_weather...

    The history of surface weather analysis concerns the timetable of developments related to surface weather analysis. Initially a tool of study for the behavior of storms, surface weather analyses became a work in progress to explain current weather and as an aid for short term weather forecasting .

  7. Surface map - Wikipedia

    en.wikipedia.org/wiki/Surface_map

    A 3D surface map of Mt. St. Helens with a 2D contour map above for comparison. In mathematics, geology, and cartography, a surface map is a 2D perspective representation of a 3-dimensional surface. [1] Surface maps usually represent real-world entities such as landforms or the surfaces of objects.

  8. Moody chart - Wikipedia

    en.wikipedia.org/wiki/Moody_chart

    In engineering, the Moody chart or Moody diagram (also Stanton diagram) is a graph in non-dimensional form that relates the Darcy–Weisbach friction factor f D, Reynolds number Re, and surface roughness for fully developed flow in a circular pipe. It can be used to predict pressure drop or flow rate down such a pipe.

  9. Surface plot - Wikipedia

    en.wikipedia.org/wiki/Surface_plot

    Surface plot may refer to: Surface plot (mathematics), a graph of a function of two variables; Surface plot (graphics), the visualization of a surface;
