Figure 6 Possible values ​of maximum daily precipitation
forecast for the next 10 years in the DMQ. The figure shows the
values ​of extreme events expected during this period, since
Table 7
CONCLUSIONS
The results show, that for the next 10 years, the DMQ south, will be possible find extreme events of
23.7ºC, and according to the A2 and B2 scenarios could be recorded 24.3 C and 24.2ºC respectively,
ie. an eventual increase of about 10 west to 7º east over the average. While in the north-east, a warm
region, it is possible to find extreme values up to 8ºC more than average. In the case of minimum
temperatures is expected an increase of nearly 7 all over the region.
In the case of the precipitation is not found a systematically forcing to suggest that its value increases
or decreases, so were used a Fretchel distribution. In the south region which is the rainiest, is
expected to register single events to up 100 mm/day, may register 156 mm/day. As for the northeast,
can record maximum of 56.5 mm/day. It should be noted that in this area the rains are often scarce.
Thus, it is important to note that, although this study predicts large magnitudes events, they have an
occasional nature, but nonetheless must be taken into account by stakeholders and decision makers
for proper planning.
This research was funded by CDKN within the
“Vulnerability Study of DMQ." And it was done under the
direction of SEI Institute, and the collaboration of the Red
de Unviersidades Frente al Cambio Climático.

Fig.4 presented maximal mensual values of Solar Radiation and Temperature, by station. Two
stations are located in the valleys and have a higher average (and maximum)
temperature, while others are located within the urban area of Quito. The correlation
between these variables is evident R whose coefficients vary between 0,05 and 0,08.

Maximal mensual values of Solar Radiation and Temperature, by
station. Two stations are located in the valleys and have a higher
average (and maximum) temperature, while others are located within
the urban area of Quito. The correlation between these variables is
evident R whose coefficients vary between 0,77 and 0,78.
Annual variation
CONCLUSIONS
 Although solar radiation is proportional to the height, it becomes clear that
in the studied data the most influential variable is the temperature.
 Likewise, it is interesting to observe that the maximum radiation values
occur in the months of March that not only correspond to the equinoxes,
but also the beginning of the rainy season in Quito. It is said that the water
vapor drops amplified radiation as a magnifying glass for a few moments.
This relates to the vernacular knowledge of hazard of the "sun of waters”
(sol de aguas) referred to the sun that is received before a storm (pres.
obs.).
 Finally, since the solar radiation is too sensitive to extreme temperature
variability, it is important to consider, its health effects in the context of a
pessimistic climate change scenario
