in Modeling Earth Systems (JAMES), Journal of Geophysical Research The interannual rainfall variability shows a decrease in rainfall with time over Moundou. Though lower mean rainfall rates (Diallo et al., 2014; Maharana et al., 2018), the variability is comparable to the cities in southern Chad (Table 1). In addition, it is very useful for data sets without a seasonal cycle and having a monotonic trend. Any queries (other than missing content) should be directed to the corresponding author for the article. Climate and Average Weather in Chad. A. Y. The present study is an attempt to study the change in the climate pattern of the different cities of Chad, which represents different climatic zones within Chad. Collins (2011) reported significant warming over the northern and southern parts of Africa in recent decades; however, the wintertime warming is more significant over northern Africa. rain Weather Chad, Satellite Weather Chad, Weather Forecast, Rainfall, Clouds, Sun in Chad - Source: SAT24.com Section 3 describes the results and discussion while the summary and concluding remarks are provided in section 4. Entdecken Sie Rainfall von Chad Beall bei Amazon Music. The northern areas tend to experience much higher temperatures. The largest variability is during the wet period followed by the dry and recovery periods (Figure 5). The temperature anomalies are greater than 1 standard deviation after the year 2000, which is an indicator of the recent temperature rise. The interannual variability in the form of standardized anomaly of rainfall and temperature are analyzed over the major cities of Chad (Figure 2). Past Weather in N'Djamena, Chad — Yesterday and Last 2 Weeks. Publish your articles and forecasts in our website. With an average of 6.5h of sunshine, August has the least sunshine of the year in N'Djamena, Chad. The WAM process brings rain over Chad during summer (JJA), which is the major source of water over Chad, while the rest of the months are dry. Physics, Comets and Ndjamena experiences mean rainfall of 38 cm/year during the wet period with very high temporal variability. • Rains are likely to be less uniformly distributed in the future, as dry spells in the rainy season are projected to substantially increase. On the contrary, Faya (closer to the Sahara desert) shows a decline in rainfall during the dry and recovery phase when compared to the wet period.

Weather Today/Tomorrow ; Hour-by-Hour Forecast ; 14 Day Forecast ; Yesterday/Past Weather; Climate (Averages) Time Zone ; DST Changes; Sun & Moon . Most of the excess rainfall years (rainfall greater than 1 standard deviation) are observed during 1950–1980. Similar to the annual averaged temperature trends, the seasonal temperatures are also increasing over all the locations (Table S1). The mean JJA rainfall is used for the plotting of PDF. The increasing rate among the stations varies from 0.82 mm per decade in Mongo to 2.32 mm per decade in Abeche. Mongo, in eastern Chad, also shows similar rainfall distributions to that of Abeche and Ati. During June, Abeche, Lere, Mongo, and Moundou show statistically decreasing trends of magnitude 0.46, 0.47, 0.47, and 0.69 mm per decade. and Paleomagnetism, History of Therefore, the climate change signal detection over major cities, which are scattered within different climatic zones, is of utmost importance. World, Europe Africa Japan - Source: SAT24.com Effective rainfall and initial soil moisture content. Sarh rainfall during the wet period is 67cm/year, which decreases to 62 cm/year during the dry period and then 54 cm/year during the recovery period. Time/General; Weather . Precipitation in Chad decreased to 0.14 mm in December from 0.23 mm in November of 2015. At the towns of Moundou and Sarh, in the wet and dry tropical zone, between 32 and 48 inches (800 and 1,200 mm) of rain falls annually between May and October. The fliers which are outsides these limits are indicate by cross. The rainfall distribution at Ati is similar to Abeche and shows highest peak during the wet period, which further decreases during the recovery period and dry period. The further declining of rainfall over Sarh and Lere during recovery period slows down the overall rainfall recovery over Chad. Rainfall shows a significant decreasing trend especially over cities close to Lake Chad (Lere, Mondou, Mongo, and Sarh), whereas no significant trend is observed for cities farther from the Lake. This is important, as the Lake Chad is close to Ndjamena represents the major fresh water source. These better process‐based understanding of this variability will help to develop the local scale mitigation strategies and adaptation technologies in this region. A substantial rise in air temperature is observed after 1980–1985, reflecting the gradual rise of temperature in recent times. This method is robust to the effect of the outliers in the data and avoids a distribution for the residual. Between 2000 and 2009, the average rainfall in Chad’s crop growing regions was about 13 percent lower than the 1920–1969 mean average, which is more than 1.3 standard deviations below this mean. In general, the Sahel and West African region have experienced a decreasing trend in rainfall, which has recently begun to increase (Maharana et al., 2018; Trenberth et al., 2007). However, a consistently increasing trend in temperature is found across all cities. Most locations during the recovery period show an increase in the rainfall rate although with less magnitude as compared to the wet period except Lere and Moundou, which reported further decline in the rate of rainfall.

The current rainfall in Chad Basin is 350 mm/year (Kutzbach, 1980). Decreasing trends of 0.66 mm per decade during July is observed over Moundou, while 0.05 and 0.96 mm per decade during August over Faya and Sarh, respectively. The rainfall behavior is similar to Ati, Abeche, and Moundou, except that standardized rainfall anomalies are much higher in recent years. The standardized anomaly time series of temperature and precipitation are prepared by subtracting the long‐term mean from the monthly time series (anomaly) and then dividing this anomaly with the standard deviation of the same monthly time series. Geophysics, Geomagnetism The highest (lowest) rising temperature trend is found during MAM (DJF) for all the locations, which are statistically significant at 0.001 level. Rainfall in Chad declined rapidly between 1950 and the mid-1980s, recovered in the 1990s, and declined again in the 2000s. The impact of the degrading environment on migration is stark with a new phenomenon of moving not only for greener pastures but also for life safety, experts say. Lake Chad is a shallow lake, which has almost halved over the past 50 years, however, its size varies between the seasons and from year to year according to rainfall. Rainfall anomalies in the Lake Chad Basin in Africa in 2019.Given its position in developing nations, the water that moves through the basin’s river systems after the rainy season has an out-sized impact on the human beings who live there. The PDF of Ati shows that mean annual rainfall is lower than Abeche for all the three periods (Figure 4). The dry season is often windy, and cooler during the evenings. Unexpectedly, the rainfall increases to 66 cm/year during the dry period, where the entire country experiencing decline in rainfall. Intergovernmental Panel on Climate Change 2007 (Pachauri & Reisinger, 2007) reported a contrasting view point of change in the rainfall trend over Africa. Although all these locations are close, the position of Mongo is further south and receives higher rainfall relatively (i.e., 56 cm/year in wet period, 48 cm/year in dry period, and 53 cm/year during recovery period). Recently, rainfall extremes are found to increase over western part of South Africa (Kruger, 2006). The temporal variability of rainfall during the dry and recovery periods is reasonably similar. These characteristics have been reported from the analysis of long‐term rain‐gauge, observational and reanalysis data sets (Le Barbé et al., 2002; Maharana et al., 2018). Lake Chad (French: Lac Tchad) is a historically large, shallow, endorheic lake in Africa, which has varied in size over the centuries. The monthly trend analysis for the entire study period shows the major rainfall‐contributing month toward the total annual rainfall trend (Table S3). The temporal variability is lowest for the recovery period and highest for the wet period. Global temperatures have been increasing since 1850, with an increase of 0.75 °C experienced between 1850–1899 and 2001–2005 (Trenberth et al., 2007). The best time of year to visit Mao in Chad. (1896-1977), Chinese Journal of Geophysics (2000-2018), International Similar trend analysis of the seasonal rainfall trend (Table S1) shows that the JJA rainfall over all the locations is also decreasing. Direct access to our calendar releases and historical data. This is the major reason why the rainfall over Faya does not show any statistically significant and the rainfall variability is very high. The long‐term trend of annual, seasonal as well as the monthly trends rainfall and temperature are over the major cities have been analyzed to compute the annual, seasonal as well as the monthly trends using a well‐adopted nonparametric MK test (Alexander et al., 2006; Maharana et al., 2018; Tan & Gan, 2015; Westra et al., 2013). Rainfall increases with the advancement of WAM and peaks in August and decreases thereafter. The stronger decreasing rainfall trends over Lere and Moundou during the recovery period is the reason of suppressing the higher rainfall trend over Chad. Afterward, the rainfall decreases subsequently with seven deficient years (two excess years) between 1976 and 2006. (a) Map of Chad with the major cities. It's always hot in Chad, but the best time to go is from November till February. Related to Geologic Time, Mineralogy It is interesting to observed that the monsoonal winds from Atlantic Ocean bends toward right in the northeast direction once it crosses the equator (Maharana et al., 2018). The declining trend during June to August (JJA) is confirmed by the lower negative Z value (Table S1). The Lake Chad Basin is one of Africa’s largest closed sedimentary groundwater basins and encompasses three climate zones: the Saharan desert climate in the north, the Sahel in central Chad with its wet and dry seasons, and the Sudan zone in the south with a hot, wet-dry tropical climate. Ndjamena receives the highest mean rainfall (4.47 cm per month) with the strongest rainfall variability among all locations (1.87 cm per month). Temperature (Figure 3b), however, does not show much variability among the stations or within the stations. K. C. P. and P. M. conceptualized the idea of the work. Further, the interannual variability of rainfall (Figure 3a) and temperature (Figure 3b) have been analyzed using box‐whiskers over the eight locations. Though Chad national rainfall index fluctuated substantially in recent years, it tended to decrease through 1968 - 2001 period ending at 648.2 mm/year in 2001. Other cities are scattered over the southern part of Africa below 15°N, where most of the WAM activity occurs (Maharana et al., 2018). Composition and Structure, Atmospheric Be aware that the country almost comes to a complet standstill during the Islamic holy month … The mean temperature over these cities ranges between 27.10 °C (Moundou) and 30 °C (Mongo).
