    Illinois' ecology is in a land area of 56,400 square miles (146,000 km 2); the state is 385 miles (620 km) long and 218 miles (351 km) wide and is located between latitude: 36.9540° to 42.4951° N, and longitude: 87.3840° to 91.4244° W, [1] with primarily a humid continental climate.

    Monsoon Depression near Bangladesh. The monsoon trough, also known as the Intertropical Convergence Zone (), is depicted by a line on a weather map showing the locations of minimum sea level pressure within the monsoon region, and is a convergence zone between the wind patterns of the southern and northern hemispheres.

  4. Convergence zone - Wikipedia

    en.wikipedia.org/wiki/Convergence_zone

    A convergence zone in meteorology is a region in the atmosphere where two prevailing flows meet and interact, usually resulting in distinctive weather conditions. [1] This causes a mass accumulation that eventually leads to a vertical movement and to the formation of clouds and precipitation . [ 1 ]

  5. Intertropical Convergence Zone - Wikipedia

    en.wikipedia.org/wiki/Intertropical_Convergence_Zone

    The Intertropical Convergence Zone (ITCZ / ɪ tʃ / ITCH, or ICZ), [1] known by sailors as the doldrums [2] or the calms because of its monotonous windless weather, is the area where the northeast and the southeast trade winds converge. It encircles Earth near the thermal equator though its specific position varies

  6. Köppen climate classification - Wikipedia

    en.wikipedia.org/wiki/Köppen_climate_classification

    This climate has no natural seasons in terms of thermal and moisture changes. [10] When it is dominated most of the year by the doldrums low-pressure system due to the presence of the Intertropical Convergence Zone (ITCZ) and when there are no cyclones then the climate is qualified as equatorial. When the trade winds dominate most of the year ...

  7. Monsoon trough - Wikipedia

    en.wikipedia.org/wiki/Monsoon_trough

    August position of the ITCZ and monsoon trough in the Pacific Ocean, depicted by area of convergent streamlines in the northern Pacific. The monsoon trough is a portion of the Intertropical Convergence Zone in the Western Pacific, [1] [2] as depicted by a line on a weather map showing the locations of minimum sea level pressure, [1] and as such, is a convergence zone between the wind patterns ...

  8. Climate of Illinois - Wikipedia

    en.wikipedia.org/wiki/Climate_of_Illinois

    Illinois averages around 50 days of thunderstorm activity a year which put it somewhat above average for number of thunderstorm days for the United States. Illinois is vulnerable to tornadoes with an average of 54 occurring annually, which puts much of the state at around 9.7 tornadoes per 10,000 square miles (30,000 km 2) annually.

  9. Thermal equator - Wikipedia

    en.wikipedia.org/wiki/Thermal_equator

    This region is known as the Intertropical Convergence Zone. This zone is the result of trade winds from the northern and southern part of the hemisphere eventually joining together. [1] Still another definition states that the thermal equator is the latitude at which insolation is identical throughout the year.
