Comparison of chemistry and physics. Chemistry and physics are branches of science that both study the behavior of matter. The difference between the two lies in their scope and approach. Chemistry focuses on describing matter by its intrinsic behavior within itself as an entity, or the systems that compose matter.
Understanding basic thunderstorm formation and structure can help you make safe decisions. Thunderstorms are formed by a process called convection, defined as the transport of heat energy. Because the atmosphere is heated unevenly, an imbalance can occur which thunderstorms attempt to correct. Three things are needed for convection to be a significant hazard to flight safety: moisture, lift and instability. MoistureâSufficient moisture must be present for clouds to form.
Stronger thunderstorm cells are capable of producing tornadoes and waterspouts. There are four types of thunderstorms: single-cell, multicell cluster, multicell lines, and supercells. Supercell thunderstorms are the strongest and the most associated with severe weather phenomena. Mesoscale convective systems formed by favorable vertical wind shear within the tropics and subtropics are responsible for the development of hurricanes.
