- - - - intintertropical convergence zone
      - where Norteast and S.E wind meet near equator
      - Is low-prwesure zone
      - shift to N&S of Equator based on position of sun
      - during z shift, length & magnitude of rainy season decrease on the "Line of z Shift"
      - cross equator when it go toward N, then central H.land, S.E H.land, l.land recive rain(Mar-Sep)
    - - Summer( June-Aug)
        
        From mid-June to mid-Sepr, except lowlands in Afar and Southeast,all receive rainfall
        
        Atlantic ocean( Equatorial Westerlies /Guinea
        monsoon) &Indean ocean ( Easterlies) wet air flow to north
        
        Atlantic contribut a lot than indean ocean for ethio Kirmt
      - Autumn (Sep- Novr)
        
        b/n summer and winte
        
        ITCZ shift towards equator from Norh
        
        this weakening the equatorial westerlies,so region is W that depend in it fr rain will loss it
        
        it a showers the lowlands in southeastern part of Ethiopia.in its way tward south
      - Winter (Dec-Feb) bega
        
        ITCZ& sun are over south of equator
        
        northeasterly winds( from Asia) cover ethio
        
        have no significant coverage of rain except Afar lowlands and the Red Sea coastal
        areas.
      - Spring (Mar- May) seday/belg
        
        ITCZ& sun are over equator while shifting north from south.
        
        result in Konger & warmer days
        
        northeast trade wind is very
        reduced.
        
        southeasterlies provide rain to H.land of ethio including Somali, S.east low land
- - - - Average temp change wz change in altitude
      - 6.5 c/km
      - Dry Adiabatic L.R
        
        Temp change due to expansion ( kizkaze) or compression of air molecule( muket) wz change in altitude
        
        Unsaturated air
        
        10c/ km

      - Environmental L.R
        
        Atmosphric L.R or Normal L.R
        
        calm air
        
        6.5C/km
  - - - Equal day& night length
      - Sun strike equator twice a year
        
        Vernal( spring)
        
        Experience in North hemisphere, when sun are over equator as it go from S to N hemisphere
        
        Offset( begin) is March 21
        
        Autumn
        
        Happen when sun cross equator as it moves to south
        
        Start Sep 23rd
    - - When sun cross N & S point of the earth ( make 90 degree)
      - Unequal day & night in hemisphere
      - Summer solstice
        
        Tropic of cancer experience long daylight
        
        Jan 21st
      - Winter solstice
        
        Sun will be over tropic of Capricorn
        
        Winter in N.H & summer in S.H
