Oceans and seas significantly impact continental weather, withevaporation from the sea surface driving cloud formation andprecipitation. Tropical cyclones, warm-core low-pressure systems, formover warm oceans where temperatures exceed 26°C, precipitated by therelease of latent heat from condensation. These cyclones, known byvarious names depending on the region, have organised circulations anddevelop primarily in tropical and subtropical waters, except in regionswith cooler sea surface temperatures and high vertical wind shears. Theyreach peak intensity over warm tropical waters and weaken upon landfall,often causing extensive damage before dissipating.
The Philippines frequently experiences tropical cyclones (calledbagyo - pronounced /baɡˈjo/, [bɐɡˈjo] - in the Filipinolanguage) because of its geographical position. These cyclones typicallybring heavy rainfall, leading to widespread flooding, as well as strongwinds that cause significant damage to human life, crops, and property.Data on cyclones are collected and curated by thePhilippineAtmospheric, Geophysical, and Astronomical Services Administration(PAGASA).
This package contains Philippine tropical cyclones data from 2017 to2020 in a machine-readable format. It is hoped that this data packageprovides an interesting and unique dataset for data exploration andvisualisation as an adjunct to the traditionalirisdataset and to the currentpalmerpenguinsdataset.
You can installbagyo fromCRAN with:
install.packages("bagyo")You can install the development version ofbagyo from thepanukatanr-universe with:
install.packages("bagyo",repos= c('https://panukatan.r-universe.dev','https://cloud.r-project.org'))
Once thebagyo package has been installed, thebagyo dataset can beloaded into R as follows:
