This hypothesis commenced with the investigation of hurricane frequency during El Nino Southern Oscillation (ENSO) events between 1958 and 2007 in the six tropical cyclone basins (North Atlantic, Western North Pacific, Eastern North Pacific, North Indian, South Indian, and South Pacific). Data was gathered from international warning centers including the National Hurricane Center and the Joint Typhoon Warning Center. In addition to the relationship study of hurricane frequency and ENSO events, sea-surface temperature was also considered.
The science described here was used as the basis for developing a survey to assess secondary school students' understanding of the two phenomena. Personal interviews involved 50 students from eight countries at the Global Learning and Observations to Benefit the Environment Learning Expedition in Cape Town, South Africa. It found that high school students' perception of basic hurricane formation, relationship to ENSO events and risks were accurate. However, 34% and 72% of the respondents respectively highlighted using student research to supplement academic/hurricane learning or wanted incorporating in-class exercises with practical field-based learning. This general under-standing opens up future research into assessing hurricane instructions on students' conception.
