Numerous studies have been conducted to document long-term trends in tropical cyclone (TC) activity. However, the eastern Pacific has not received as much attention as other basins. Here the authors attempt the identification of TC formation in the Mexican eastern Pacific Ocean before 1950. Using bibliographical and historical file consultation, they constructed a catalog of events related to intense storms and possible TCs that made landfall on the Mexican Pacific coasts. Between 1536 and 1948 they found a total of 119 events related to TCs. Then, using the Saffir-Simpson scale and the climatology of the region as the criteria to evaluate each event, they found 85 TCs. Furthermore, they constructed a historical time series of TCs between 1701 and 2010. The spectral analysis showed periodicities of -2.6,4,5,12,16,39, and 105 years that coincide with some large-scale climatic phenomena and also with solar activity. In particular, the ~12-yr cycle is the most persistent periodicity in this study.

“…The rainfall pattern in this region is affected mainly by the influence of trade winds and TCs (García-Oliva et al 1991). The climate in the Jalisco coast is subhumid and warm and is present in 25% of the state's surface.…”

“…One location was a flat hilltop, and the second was a south‐facing mid‐slope (27°) of a small watershed that has been extensively studied for a long‐term project on ecosystem function. Distance between the two locations was 300 m. Mean annual temperature is 24.9 °C and the mean annual precipitation is 763 mm, with the rainfall concentrated in a clearly marked wet season that lasts from June to October, showing a peak in September (García‐Oliva et al ., 1991). The dominant vegetation is tropical deciduous forest, where most tree species are leafless during the dry season.…”

Aim To assess the hypothesis that free-living prokaryotes show a pattern of 'no biogeography' by examining the scaling of soil prokaryotic diversity and by comparing it with other groups' biogeographical patterns.Location Two sites in the tropical deciduous forest of Chamela, Jalisco, on the western coast of Mexico. MethodsWe examined the diversity and distribution of soil prokaryotes in two 8 × 8 m quadrats divided in such manner that we could sample at four spatial scales. Restriction fragment length polymorphisms of 16S rRNA genes were used to define operational taxonomic units (OTUs) that we used in lieu of species to assess diversity. ResultsWe found highly structured species assemblages that allowed us to reject multiple predictions of the hypothesis that soil bacteria show 'no biogeography' . The frequency distribution of range size (measured as the occupancy of quadrats) of OTUs followed a hollow curve similar to that of vertebrates on continents. Assemblages showed high levels of beta diversity and a non-random nested pattern of diversity. OTU diversity scaled with area followed a power function with slopes z = 0.42 and 0.47. Main conclusionsWe demonstrate a non-ubiquitous dispersal for soil prokaryotes, which suggests a complex biogeography similar to that found for terrestrial vertebrates.

“…We also establish what kind of climatic information is maintained in the record and over what spatial scales, and we unravel the large‐scale controls. As precipitation in this region is influenced by tropical storms or cyclones [ Englehart and Douglas , ; García‐Oliva et al ., ; Jauregui , ], we further inquire whether tropical storms may have influenced the isotope signal. About half of annual precipitation in the study region falls in heavy events (Figure b) often related to tropical storms or cyclones (Figures c and c).…”

Oxygen isotopes in tree rings record variation in precipitation δ¹⁸O and amount effects in the south of Mexico

[1] Natural archives of oxygen isotopes in precipitation may be used to study changes in the hydrological cycle in the tropics, but their interpretation is not straightforward. We studied to which degree tree rings of Mimosa acantholoba from southern Mexico record variation in isotopic composition of precipitation and which climatic processes influence oxygen isotopes in tree rings (δ18Otr). Interannual variation in δ18Otr was highly synchronized between trees and closely related to isotopic composition of rain measured at San Salvador, 710 km to the southwest. Correlations with δ13C, growth, or local climate variables (temperature, cloud cover, vapor pressure deficit (VPD)) were relatively low, indicating weak plant physiological influences. Interannual variation in δ18Otr correlated negatively with local rainfall amount and intensity. Correlations with the amount of precipitation extended along a 1000 km long stretch of the Pacific Central American coast, probably as a result of organized storm systems uniformly affecting rainfall in the region and its isotope signal; episodic heavy precipitation events, of which some are related to cyclones, deposit strongly 18O-depleted rain in the region and seem to have affected the δ18Otr signal. Large-scale controls on the isotope signature include variation in sea surface temperatures of tropical north Atlantic and Pacific Ocean. In conclusion, we show that δ18Otr of M. acantholoba can be used as a proxy for source water δ18O and that interannual variation in δ18Oprec is caused by a regional amount effect. This contrasts with δ18O signatures at continental sites where cumulative rainout processes dominate and thus provide a proxy for precipitation integrated over a much larger scale. Our results confirm that processes influencing climate-isotope relations differ between sites located, e.g., in the western Amazon versus coastal Mexico, and that tree ring isotope records can help in disentangling the processes influencing precipitation δ18O.
