cT= continental Tropical
cP=continental Polar
mT=maritime Tropical
there is also :
mP=maritime Polar
cA=continental Arctic
c(continental)=dry/not very humid
m(maritime)=wet/humid
T(Tropical=warm
P(Polar)=cold
A(Arctic)=very cold

Those terms likely stand for cT (constant temperature), cP (constant pressure), mT (monotonic temperature), and mT (monotonic temperature). They describe specific thermodynamic processes or conditions, such as how temperature or pressure remains constant during a process, or how temperature changes in a monotonic manner.
The air masses that have the greatest influence on weather conditions in the Midwestern US are continental polar (cP) air masses in winter and maritime tropical (mT) air masses in summer. These air masses bring contrasting temperature and moisture conditions that can lead to significant weather events like thunderstorms, snowstorms, and severe weather.
cP (continental polar) air masses bring cold and dry weather to much of the US during the winter, leading to low temperatures and clear skies. On the other hand, mT (maritime tropical) air masses bring warm and moist conditions during the summer, leading to higher temperatures and increased chances of thunderstorms and heavy rainfall.
Energy W is the ability to do work, W = -vp + cP where v is motion (velocity/speed) and p=h/w= mv is momentum. Force is the first derivative of energy, Force F = XW =[d/dr, DEL] [-vh/w, cP] = [ vp/r -cDEL.P, cdP/dr -DEL vh/w + cDELxP] F = cp/r[v/c -cos(P), -1P + v/c 1R + sin(P) 1RxP] Force = cp/r = cp/ct = p/t = mv/t = ma Motion is the change in position per unit time and is related to Force and Energy.
The four main types of air masses that affect weather are continental polar (cP), maritime polar (mP), continental tropical (cT), and maritime tropical (mT). These air masses differ in temperature and moisture content based on their source region, and they play a significant role in shaping weather patterns when they interact.
Metric Tonnes=1016 kg One tonne is 1000kg, or 1 megagram. The prefix of a lowercase 'm' indicates milli- or one thousandth, so mt would be a millitonne. A thousandth of a tonne is a kilogram, as kilogram is the base unit of mass millitonnes would never be used, they would always be called kilograms.
