“…During these dry periods, one single TC event may provide enough rainfall in a region as to make its summer rainy season quasi-normal or above-normal in the middle of a prolonged meteorological drought. This was the case of the Hurricane Alex, 2010 or tropical storm Ingrid, 2013 that affected the northeast of Mexico and produced enough precipitation to turn into normal the precipitation statistics during that summer season and recover the levels of dams during a severe drought period (Sisto et al, 2015).…”

“…TC Alex helped to recover El Cuchillo dam water levels to normal conditions, enough to provide this resource for several socioeconomic activities during the prolonged 2010-2012 drought (Magaña and Neri, 2012). Thus, TCs may be water suppliers during dry periods, ameliorating the effects of water crisis (Sisto et al, 2015). Including the effect of TCs in climate outlooks would be of great benefit in the water management plans where water distribution is frequently decided on a yearly basis, especially during periods of drought (Neri and Magaña, 2016).…”

Tropical cyclones (TCs) are essential elements of the hydrological cycle in tropical and subtropical regions. In the present study, the contribution of TCs to seasonal precipitation around the tropical and subtropical North America is examined. When TC activity over the tropical eastern Pacific (TEP) or the Intra Americas Seas (IAS) is below (abovenormal), regional precipitation may be below (above-normal). However, it is not only the number of TCs what may change seasonal precipitation, but the trajectory of the systems. TCs induce intense precipitation over continental regions if they are close enough to shorelines, for instance, if the TC center is located, on average, less than 500 km-distant from the coast. However, if TCs are more remote than this threshold distance, the chances of rain over continental regions decrease, particularly in arid and semi-arid regions. In addition, a distant TC may induce subsidence or produce moisture divergence that inhibits, at least for a few days, convective activity farther away than the threshold distance. An analysis of interannual variability in the TCs that produce precipitation over the tropical and subtropical North America shows that some regions in northern Mexico, which mostly depend on this effect to undergo wet years, may experience seasonal negative anomalies in precipitation if TCs trajectories are remote. Therefore, TCs (activity and trajectories) are important modulators of climate variability on various time scales, either by producing intense rainfall or by inhibiting convection at distant regions from their trajectory. The impact of such variations on water availability in northern Mexico may be relevant, since water availability in dams recovers under the effects of TC rainfall. Seasonal precipitation forecasts or climate change scenarios for these regions should take into account the effect of TCs, if regional adaptation strategies are implemented.

Tropical cyclones (TCs) are an important element of the climate dynamics in the tropical Americas. They produce intense precipitation during a few days of the rainy season. The contribution of tropical cyclone precipitation to seasonal accumulated rainfall may be as large as fifty per cent, particularly in the arid and semi-arid regions of northern Mexico. A positive trend in the number of tropical cyclones over the eastern Pacific, has resulted in more of these systems approaching the Baja peninsula and a positive trend in annual precipitation. However, the contribution of TCs to regional accumulated may be positive or negative depending on the trajectory followed by the system. If the TC is not close enough to the coastal region, it may induce atmospheric moisture divergence over land, reducing the chances of tropical convective activity and rainfall. Years of large but "distant to continent" TC activity result in negative anomalies in precipitation for some regions of the tropical Americas. Seasonal regional climate predictions or regional climate change scenarios provide information on TC activity but not on preferred trajectories. By means of TC cluster analysis, the preferred trajectories of TCs around the tropical Americas are explored in relation to quasi-stationary circulations at the steering level. Some ideas on how to estimate preferred TCs trajectories for a season are given.

“…Water scarcity and crises result in harmful effects on human health (risk of hunger and diseases) and/or economic activities, and these are considered the number one risk the developing world currently faces (Oyedotun 2011(Oyedotun , 2012WEF 2015;Sisto et al 2016), of which Ethiopia is not an exception. To reduce the demand and supply gap for potable water in the entire Ethiopia, the World Bank has been supporting the Government of Ethiopia through various Urban Water Supply and Sanitation Projects (UWSSP)-principally in Addis Ababa and other four main cities in Ethiopia (World Bank 2005).…”

Ensuring water availability in Mekelle City, Northern Ethiopia: evaluation of the water supply sub-project

The need and demand for water in the world are becoming acute with the growing population. This is mostly pressing in developing countries of which Mekelle City in Northern Ethiopia is not an exception. World Bank borehole-support sub-project was aimed at addressing this challenge. The evaluation of the intervention indicates that there is a significant increase in water supply in the city because of the sub-project. However, the increase in water supply has not been able to meet up with the already established and increasing demand. Coupled with this challenge are: the limited capacity of human capital and expertise that will ensure the proper management of borehole interventions; insufficient cost recovery for proper operation and maintenance of the projects; loss of land and farmlands and lack of compensations because of the projects which affect the livelihood.
