HadCM3 stands for Hadley Center Coupling model version three. This global climate model (GCM) was developed by the Met Office Hadley Center for Climate Science and Services in 2000, and was used as one of the major GCM ever since, starting from the Third Assessment Report by the Intergovernmental Panel on Climate Change in 2001. The model includes two elements – HadAm3 (for atmospheric modeling) and HadOM3 (for oceanic modeling), therefore forming a coupling assessment model. The GCM was a further development of the previous model HadCM2, also developed at Hadley (Bloom, 184).

This forms a negatively charged n-layer. On the other layer created deficiency of electrons and becomes positively charged (p-layer). When a photon of ...

1.1 Overview Quantum mechanics is a branch of Physics that deals with the behaviors of energy and matter in the smallest perspective such as the nuclear, atomic, and microscopic levels. Quantum, meaning “how much”, refers to the quantifiable units to energy and matter as observed and predicted through physics. This branch of studies stated with mathematical reasoning of certain experiments that are non-explainable through the classical mathematical methods. Physics revolutionized during the early 20th century (Coolman, 2014). Various models has been developed by scientists since them to help them in their experiments in studying particular behaviors of reaction mechanisms ...
