Course Objectives

This course will cover cloud physics, atmospheric radiation and radar meteorology with emphasis on understanding the basic concepts and physical processes. Clouds and convection are recognized as an essential component of the global climate system. Cloud systems affect incoming and outgoing radiant energy through processes of reflection, absorption and emission. Organized convection, through the release of latent heat and the redistribution of heat and momentum, has an important role in the coupling of large-scale dynamical and thermodynamical processes. Tropical precipitating cloud systems are considered to be a key factor in the surface energy budget through the modification of radiative fluxes and heat fluxes at the ocean surface. Building a solid foundation in physical principles and developing self-learning and thinking skills are the goals.

Course Design

Students are expected to come to class prepared to participate actively in the learning process. As in any professional organization, absences should be justified and promptness is standard procedure. Your homework should be done with pride and submitted on time. The policy for late assignments is stated below.

COVID-19 health and safety requirements

Students are responsible for abiding by the university’s COVID-19 health and safety expectations. All students attending this class in-person are required to:

• properly wear a face covering and/or face shield, covering the nose and mouth, while in classrooms, laboratories, studios, offices, and other learning spaces. It is important to remember that a face covering and/or face shield is required to be worn whenever you are on campus, in the presence of others, and unable to maintain physical distance.

• practice physical distancing to the extent possible;

• assist in maintaining a clean and sanitary environment;

• not attend class if you are sick or experiencing symptoms of COVID-19;

• not attend class if you have been told to self-isolate or quarantine by a health official.

• follow the faculty member’s guidance with respect to these requirements. Failure to comply constitutes disruptive classroom conduct. Faculty and teaching assistants have the authority to deny a non-compliant student entry into a classroom, laboratory, studio, conference room, office, or other learning space.
