I, facing p. 941 THE direction that the modern study of climate has taken has been dictated largely by the development of meteorological instruments, the establishment of meteorological observatories, and the collection of weather data. The catalogue of climatic elements consists of those that are customarily measured and usually includes temperature, precipitation, atmospheric humidity and pressure, and wind velocity. Increasingly, climatic studies have tended to become statistical analyses of the observations of individual elements. Because of this, climatology has been regarded in some quarters as nothing more than statistical meteorology. THE ROLE OF EVAPORATION AND TRANSPIRATIONBut the sum of the climatic elements that have been under observation does not equal climate. One element conspicuously missing from the list is evaporation. The combined evaporation from the soil surface and transpiration from plants, called "evapotranspiration," represents the transport of water from the earth back to the atmosphere, the reverse of precipitation. The rain gauge measures precipitation within acceptable limits of accuracy. We know reasonably well how rainfall varies from one place to another over the inhabited parts of the earth and also how it varies through the year and from one year to another. On the other hand, no instrument has yet been perfected to measure the water movement from the earth to the atmosphere, and consequently we know next to nothing about the distribution of evapotranspiration in space or time.We cannot tell whether a climate is moist or dry by knowing the precipitation alone. We must know whether precipitation is greater or less than the water needed for evaporation and transpiration. Precipitation and evapotranspiration are equally important climatic factors. Since precipitation and evapotranspiration are due to different meteorological causes, they are not often the same either in amount or in distribution through the year. In some places more rain-falls month after month than evaporates or than the vegetation uses. The surplus moves through the ground and over it to form > DR. THORNTHWAITE, consulting climatologist, has spent the growing seasons of I946 and I947 in experiments "fitting crops to weather" (see p. 4). RATIONAL CLASSIFICATION OF CLIMATE methods of plant physiology. Nevertheless, evapotranspiration represents the return flow of water to the atmosphere and is thus an important meteorological process.The only method so far developed that measures the actual evapotranspiration from a field or any other natu...

Exacerbation of the 2013–2016 Pan‐Caribbean Drought by Anthropogenic Warming

“…We used the UN Food and Agriculture Organization (FAO) PET formulation (Allen et al, 1998) because it is more physically realistic than the Thornthwaite (1948) equation used in the original PDSI calculation (Palmer, 1965). A key drawback of the Thornthwaite approach—especially for climate change applications—is the use of temperature as the only climate variable forcing PET, which leads to an exacerbation of the sensitivity of PET to temperature variations (Abatzoglou & Williams, 2016; Smerdon et al, 2015; Williams et al, 2015).…”

Impacts of climate projections on water balance and implications on olive crop in Minas Gerais

“…The potential evapotranspiration (ETP) was calculated using the method proposed by Thornthwaite (1948), mainly because of the low national availability of meteorological data of hard measurement and for having good results for the studied area, besides being the ETP estimation method most used in studies of climatological water balances (Sentelhas et al, 2008).…”

Impacts of climate change on the agricultural zoning of climate risk for cotton cultivation in Brazil

“…Evapotranspiration was calculated by the Thornthwaite method (Thornthwaite, 1948) adapted for Brazilian conditions (Azevedo & Silva, 2007), and water balance was determined according to Sarra model (Affholder et al, 2006), considering 50 mm of available soil water capacity. Monthly rainfall means were calculated considering daily values of 25 years, obtained from 4,000 rainfall stations, available in the Agritempo system (Brasil, 2012).…”
