The storm was able to tap into the jet stream and aim it towards the surface the phenomenon known as " Jet stream enhancement ", which usually occurs in the unstable air found in a cold front in a mid latitude cyclone.

In the Northern Hemisphere, the equinox sun peaks in the southern half ( about halfway up from the horizon at mid latitude ) of the sky, while in the Southern Hemisphere, that sun peaks in the northern half of the sky.

A solar " day " at the equator is shorter than mid latitude and this shearing is what gives rise to Joy's Law ( astronomy ) of sunspot angle .-- talk ) 17 : 57, 30 January 2016 ( UTC)

Most often sea surface temperature anomalies in the Atlantic and intensification of the mid latitude westerlies in the Pacific can bring a stable anticyclone, meaning that the pressure can remain above average for weeks, or even months at a time, allowing the heat to build and dry weather to continue during the anticyclonic system.

Within the atmosphere, this means from the surface to above the 500 hPa level, generally stopping at or defining the tropopause at around 200 hPa . Most atmospheric deep convection occurs in the tropics as the rising branch of the Hadley circulation; it represents a strong coupling between the surface and the upper atmosphere which is largely absent in mid latitudes.

Variability of anvil height ( an anvil is the large, plume-like top of a thunderhead ) also contributes 45, 000 feet ( 13, 715 m ) is very common in the mid latitudes for warm season thunderstorms, but the anvil height can range from 35, 000 feet ( 10, 665 m ) to a current record of 78, 000 feet ( 23, 770 m ).
