Weather System

Weather

The weather system includes the dynamics of the atmosphere and its interaction with the oceans and land. Weather includes those local or microphysical processes that occur in minutes through the global-scale phenomena that can be predicted with a degree of success at an estimated maximum of two weeks prior. The Weather theme is important to the NASA Earth Science for two reasons. First, the improvement of our understanding of weather processes and phenomena is crucial in gaining an understanding of the Earth system. It is directly related to the Climate and Water/Energy Cycle Themes. In both cases, the dynamics are to a large degree controlled by "weather processes." Second, there is an infrastructure in the U.S. for operational meteorology at NOAA, the FAA, the DoD, and others that requires the introduction of new technologies and knowledge that only NASA can develop.

Eucalyptus and related trees

Eucalypts are tree species belonging to three closely related genera, Angophora, Corymbia and Eucalyptus.

Of these, Eucalyptus has the most species, the most-widely planted species and the biggest trees, so "eucalypt" refers most often to Eucalyptus.

To survive frequent bushfires the Eucalypts have developed a 'lignotuber' which is a resovoir of buds so that when small branches are destroyed a new bud can replace it.

Probability theory

Probability theory is the mathematical study of phenomena characterized by randomness or uncertainty.More precisely, probability is used for modelling situations when the result of an experiment, realized under the same circumstances, produces different results (typically throwing a dice or a coin). Mathematicians and actuaries think of probabilities as numbers in the closed interval from 0 to 1 assigned to "events" whose occurrence or failure to occur is random.

Monsoon

A monsoon is a periodic wind, especially in the Indian Ocean and southern Asia. The word is also used to label the season in which this wind blows from the southwest in India and adjacent areas that is characterized by very heavy rainfall, and specifically the rainfall that is associated with this wind.
