Editing Nimbostratus cloud (section)

== Relation to other clouds ==
Multi-level nimbostratus is physically related to other stratiform genus-types by way of being non-convective in nature. However, the other sheet-like clouds usually each occupy only one or two levels at the same time. [[Stratus cloud|Stratus]] clouds are low-level and form from near ground level to {{convert|2000|m|ft}} at all latitudes. In the middle level are the [[Altostratus cloud|altostratus]] clouds that form from {{convert|2000|m|ft}} to {{convert|7000|m|ft}} in polar areas, {{convert|7000|m|ft}} in temperate areas, and {{convert|7600|m|ft}} in tropical areas. Although [[Altostratus cloud|altostratus]] forms mostly in the middle level of the troposphere, strong frontal lift can push it into the lower part of the high-level. The main high-level stratiform cloud is [[Cirrostratus cloud|cirrostratus]] which is composed of ice crystals that often produce halo effects around the sun. [[Cirrostratus cloud|Cirrostratus]] forms at altitudes of {{convert|3000|to|7600|m|ft}} in high latitudes, {{convert|5000|to|12000|m|ft}} in temperate latitudes, and {{convert|6100|to|18000|m|ft}} in low, tropical latitudes. <!-- <ref name="nws-jetstream" /> -->  Of the non-stratiform clouds, [[Cumulonimbus cloud|cumulonimbus]] and [[Cumulus congestus cloud|cumulus congestus]] are the most closely related to nimbostratus because of their vertical extent and ability to produce moderate to heavy precipitation.  The remaining cumuliform ([[Cumulus cloud|cumulus]]) and stratocumuliform ([[Stratocumulus cloud|stratocumulus]], [[Altocumulus cloud|altocumulus]], and [[Cirrocumulus cloud|cirrocumulus]]) clouds have the least in common with nimbostratus.
