Rainfall droughts can occur in any region of the planet, regardless of its climatic rhythm, and drought indices are able to estimate the characteristics of these phenomena, determining the beginning and end, as well as their durability over time. Time series are an important statistical tool for extracting information from past data and making projections from this information.

The Pacific Decadal Oscillation (PDO) is defined as the first principal component of the EOF (Empirical Orthogonal Function) of the SST (Surface Sea Level Temperature-) in the North Pacific. Several studies show that it is significantly associated with snowfall in the Arid Andes. The present work proposes to describe the process that leads to said teleconnection, that is, the spatio-temporal association of the PDO with the factors that affect rainfall in them. It was concluded that the PDO: Increases SST in the ENSO area, has an inverse relationship with MLSP and westerlies, weakening ASPSO and 500mb geopotential.

Rainfall is the meteorological phenomenon that occurs most frequently, so it is one of the climatic elelments that presents the greatest spatial and temporal variation. To analyze the spatial and temporal variability along the Cundiboyacense high plateau, a regionalization of rainfall patterns was carried out through the PCA Principal Component Analysis method, based on monthly climatic series of monthly precipitation, from 21 stations.

The state of Jalisco presents a high climatic diversity due to its geographical location and its varied landscape. The recorded data, from 1961 to present date, have several problems, the most important is the large amount of missing data. To circumvent this issue, a two-stage method for estimating missing data is proposed; the first uses an unsupervised algorithm; hence it does not require historical data. The second uses supervised interpolation for correcting the error from the first one.

The management of meteorological information is essential in the planning of agricultural systems. For this reason, it is necessary to have meteorological series with long, complete and quality data. In its absence, an alternative is to use of reanalysis series, provided they present good precision to the meteorology from which they are evaluated. In this research, the precipitation, maximum and minimum temperatures of the ERA 5, Merra 2 and Terra climate reanalyses were assessed, on a daily and monthly basis, with respect to the series of the INIA CENIAP station, in Venezuela.

This article estimates the behavior of the weather in Seville during the 16th century. In particular, the period between 1519-1522, which coincides with the first circumvallation of the globe by Elcano Magallanes. The beginning and end of said voyage was the river port of Seville, exactly 500 years ago this year. The urban conditions of the city in the face of climatic risks are described and documentary information, collected from different historical sources, details the most relevant weather. This enables us to examine the climate history within the context of the general history of the city.

At the global level, agriculture is the main consumer of water with more than 70\% of the use, using it with an efficiency of around 40\%. The decrease in the water available for agriculture requires that the efficiency of use be increased. One way to increase this efficiency is to accurately quantify the water needs of crops for proper irrigation management. Water needs can be estimated from the reference crop evapotranspiration value (ETo).
