Evidences for a shift in barometric pressure, air temperature and rainfall patterns circaand its possible relation to what is considered a significant correlation coefficient activity. Evidencias de un cambio en los patrones de la presión atmosférica, la temperatura del aire y la precipitación pluvial alrededor de y su posible relación con la actividad solar. El Hombre y su Ambiente. Recibido: 19 de julio de Aceptado: 1 de abril de A survey of meteorological stations worldwide located showed that nearly half of the stations presented a pattern change in the correlations between the sunspot number and barometric pressure, air temperature and precipitation, around This change was mainly from a negative correlation to a positive correlation.

Furthermore, we also found strong correlations between sunspots and pressure and precipitation in both tropical and extratropical latitudes; for the temperature the strong correlations appear mainly in extratropical zones. Keywords: Climatic reversal, climatic variability, sunspots. Este cambio consistió principalmente en un cambio en el signo de la correlación, de negativo a positivo.

Recently, Mendoza and Ramírez showed that what does dominant artery times of low solar activity sunspots dominate over bright features within the time scale of solar cycles and viceversa. It is this last change of the Sun's behavior, which occurred aroundthe one that has been obviously most documented. In fact several papers have reported that sign reversals in meteorological variables such as temperature, rainfall, water level, etc.

Starr and OortKing, Eddy and King et al. King et al. Clayton observed a similar shift in the apparent dependence of water levels in Lake Victoria after It is the purpose of the present paper to assess if the claimed change in patterns of what is considered a significant correlation coefficient main meteorological variables, namely barometric pressure, temperature and precipitation, ocurred around We surveyed meteorological stations worldwide located for barometric pressure, temperature and precipitation data Clayton,and From these, a time series of five-year moving averages for each of the variables was computed; this was performed in order to smooth the original series.

Fig 1a shows an example for the barometric pressure in La Habana Cuba; Fig. Linear correlations for the five-year averages -of each of what is considered a significant correlation coefficient three meteorological variables considered- versus R z were performed and the correlation coefficients were computed. These analysis were performed separately for the data from to and for those from to Histograms of the correlation coefficients that included data of the stations considered were plotted for each of the former periods and a non-parametric test Kruskal-Wallis' ANOVA was performed.

This test was chosen because a prior assumption of normal distribution is not needed. In nearly half cause-and-effect relationship between the two variables the stations the plots showed a change in the patterns of the meteorological variables within the period to ; therefore the data were divided in two periods to and best restaurants in venice santa monicaand the correlations between the meteorological parameters and the sunspots numbers were computed separately for each period.

The results appear in Tables 12 and 3 for the barometric pressure, the temperature and the precipitation respectively. These tables contain the localities and countries, their geographical coordinates, their correlation coefficients for both periods and the number of five-year average data pairs considered for each locality. These tables show that the change of pattern occurs either as a sign reversal of the correlation coefficient -positive to negative or viceversa- or as a variation of the amplitude of the correlation coefficients, i.

These results are suminarized in Table 4 as percentages of the stations where changes occurred. The results of tables 12 and 3 are also depicted in Figs, 23 and 4 respectively, and a summary is presented in Table 5 which contains the sign of the correlation coefficients -either positive or negative- between the meteorological parameter and the sunspot numbers for two periods I from y and II from to The what is considered a significant correlation coefficient -converted to percentual correlation coefficients- were divided into intervals for each of the three meteorological variables and a code was employed in order to show whether the values ocurred within the tropical zone or in northern or southern extratropical locations.

Also in agreement with Figs. We notice that for the barometric pressure during period I the strongest negative correlation occurred in the tropical zone zone I and a weak correlation exists in the southern extratropical zone 2Swhile the strongest positive correlation occurred in the northern extratropical zone 2N. For the period II both correlations hold in the same zones but they have weakened.

For the temperature in period I the strongest negative correlation is found in both southern and northern extratropical zones, while the strongest positive correlations are found in the northern extratropical zones. For period II the strongest negative correlations occurred in the southern extratropical zone, and a weak correlation is in the northern extratropical zone, while a positive correlation is found in the tropical zone. For precipitation, during the period I the what is considered a significant correlation coefficient correlation is strongest in both northern and southern extratropical zones and there is a weaker positive correlation in the tropical zone.

For period II the strongest negative correlations are found in the tropical and northern extratropical regions. For the three variables here considered, correlation coefficient histograms Figs. On the other hand, the histograms for the first period are close to a rectangular distribution and so higher frequencies of high correlations -in absolute values- occurred during this period. Thus, according to this latter test, the claimed change in climate variables only holds for the correlation coefficients of air temperature vs sunspot numbers.

For most of the stations that presented a change of pattern around see Table 4the change was from negative to positive; this effect is particularly noticeable in temperature. It should be remembered that several authors have reported regional changes of pattern from positive to negative around in various meteorological variables King, ; ; King et al.

Furthermore in a global context it has also been shown that a change of pattern from positive to negative should have occurred around Mendoza and Ramírez, It has been suggested that only in the equatorial regions there is a significant correlation between the sunspot cycle and the meteorological variables, specially the temperature, while from subtropical to polar latitudes the magnetic cycle masks the sunspot cycle Willett Table 5 indicates that the strongest correlations -either positive or negative- are present in both extratropical and tropical zones for temperature, and also appear in both extratropical regions for precipitation.

In the present study the correlations for temperature found in the tropical zones are weak and this trend is opposite to the results of previous works Schostakowitsch, However, both for barometric pressure and for precipitation the correlations with the sunspots cycle are very strong in the tropical zone even though the regions which present such correlations are less extensive in longitude and latitude than the areas with strong correlations in the extratropical latitudes.

For the temperature the strong correlations appear mainly in extratropical zones. World Weather Records. Smithsonian Institute. On the secular variation on rainfall at Adelaide, Australia.
