Atmospheric Science Major

Join a community of dedicated minds shaping the future of weather and climate

Students in Atmospheric Sciences study the behavior of weather and climate while gaining experience in the analysis, interpretation and forecasting of meteorological events.

Major in Atmospheric Science

Bachelor of Science (B.S.)

The Bachelor of Science in Atmospheric Science at Cornell University prepares students to understand and analyze weather and climate systems. The program offers experience in interpreting and forecasting meteorological events. Students work hands-on with weather and climate models, datasets and state-of-the-art analysis software. Many students engage in undergraduate research

The curriculum is designed with two primary objectives. First, the core program aligns with the standards set by the American Meteorological Society (AMS) and fulfills the qualifications for employment in meteorology, including positions with the National Weather Service (NWS) and various consulting and professional meteorological services. 

Second, students planning to pursue graduate studies will be well-equipped for advanced education, often supplementing the core curriculum with additional courses in mathematics, physics, and atmospheric science. Those interested in a broader exploration of environmental topics may also take courses offered through the separate Earth and Atmospheric Sciences major, which can be completed alongside the atmospheric sciences prorgram.

CALS seeks students who maintain a rigorous high school curriculum and demonstrate an outstanding record of academic achievement. Admissions requirements include:

  • 4 Units of English

  • 4 Units of Mathematics (including calculus, BC calculus recommended)

  • 3 Units of Science (including biology, chemistry, and physics)

  • An additional unit of science is strongly recommended

For a list of requirements for this major, please visit the B.S. Atmospheric Sciences program page.

  • Apply the scientific method using real-world data, including formulation of hypotheses, the use of varied approaches (experimental and observational) for testing hypotheses, integration of knowledge to solve problems in atmospheric science and appropriate intergretation of data encountered in class, lab, field and/or the literature.
  • Collect, organize, analyze and interpret quantitative information meaningfully, using mathematical and/or statistical tools and computer applications as appropriate to the discipline of Atmospheric Science
  • Synthesize a cogent argument in language appropriate to the field of study, including written and oral communication skills and presentation of results using graphs and equations, when appropriate and demonstrate the ability to convey this information to scientific and other audiences.

Climate change lowers precipitation, prolongs drought in Southwest

In the late 2010s, when Assistant Professor Flavio Lehner worked for the National Center for Atmospheric Research in Boulder, Colorado, water managers often asked him about the drought in the Southwest.

NEWS SPOTLIGHT

During the worst drought since the 1960s, irrigated farms in the Northeast suffered crop losses of up to 35 percent; for unirrigated farms, field crops and pasturage losses hit as high as 90 percent across the 12 states in the region.
