Seasonal rainfall trends at Malsiras station. scale signal for annual rainfall series can be seen in Figure 8 and annual rainfall series are shown in Figures 8(a) and 8(b) show the power (absolute value squared) of the wavelet transform for the annual rainfall of all rain- gauge stations. This gives information on the relative power at a certain scale and a certain time, that means pe- riod where it oscillates with the corresponding frequency. In the case of the annual rainfall series, most of the high power (red colour) can be found concentrated within a band of 2 - 8 and 4 - 8 years at Akluj and other three stations during 1960-1980. Also higher intensity (red colour) has been observed for 2 - 8 years during recent four decades for all stations except Akluj. Due to edge effects of wavelet processing, the cone of influence which represent the periods with uninter-pretable is also shown in Figure 8(b) (hatched areas) and consequently they should be ignored in all analysis. More than 10 - 16 years periods are the apparent periodicity at the begin- ning and end of the time-series which is not real. The wavelet analysis clearly shows a noticeable change in the

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
