  2. Shipping Forecast - Wikipedia

    en.wikipedia.org/wiki/Shipping_Forecast

    This is only very rarely omitted, generally when the schedule is running late. Though occasionally played in full, it is common for only a section of the piece to be broadcast; that section being the length required to fill the gap between the previous programme's ending and the start of the forecast at precisely 00:48. [17] "Sailing By" serves ...

  3. List of free geology software - Wikipedia

    en.wikipedia.org/wiki/List_of_free_geology_software

    This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.

  4. Barometer - Wikipedia

    en.wikipedia.org/wiki/Barometer

    For example, if a barometer located at sea level and under fair weather conditions is moved to an altitude of 1,000 feet (305 m), about 1 inch of mercury (~35 hPa) must be added on to the reading. The barometer readings at the two locations should be the same if there are negligible changes in time, horizontal distance, and temperature.

  5. Barograph - Wikipedia

    en.wikipedia.org/wiki/Barograph

    A barograph is a barometer that records the barometric pressure over time in graphical form. This instrument is also used to make a continuous recording of atmospheric pressure. This instrument is also used to make a continuous recording of atmospheric pressure.

  6. Weather forecasting - Wikipedia

    en.wikipedia.org/wiki/Weather_forecasting

    Measurements of barometric pressure and the pressure tendency (the change of pressure over time) have been used in forecasting since the late 19th century. [66] The larger the change in pressure, especially if more than 3.5 hPa (2.6 mmHg ), the larger the change in weather can be expected.

  7. Drainage density - Wikipedia

    en.wikipedia.org/wiki/Drainage_density

    According to Horton’s interpretation of half of the inverse of drainage density as the average length of overland flow [2] implies that overland flow in high-drainage environments will reach a fast-flowing channel faster over a shorter range. On the hydrograph, the peak is higher and occurs over a shorter range.

  8. Illinois Basin - Wikipedia

    en.wikipedia.org/wiki/Illinois_Basin

    The Illinois Basin is a Paleozoic depositional and structural basin in the United States, centered in and underlying most of the state of Illinois, and extending into southwestern Indiana and western Kentucky. The basin is elongate, extending approximately 400 miles (640 km) northwest-southeast, and 200 miles (320 km) southwest-northeast.

  9. Tempest prognosticator - Wikipedia

    en.wikipedia.org/wiki/Tempest_prognosticator

    The tempest prognosticator, also known as the leech barometer, is a 19th-century invention by George Merryweather in which leeches are used in a barometer. The twelve leeches are kept in small bottles inside the device; when they become agitated by an approaching storm, they attempt to climb out of the bottles and trigger a small hammer which ...
