Most tropical regions experience a monsoonal climate characterised by intense seasonality of rainfall (summer wet – winter dry) [4], but paradoxically the monsoon tropics has the greatest annual variability in rainfall in the world [5].
Contemporary annual discharge measured at Huantan (1962 1987), the nearest gauging station downstream is 122 ± 21 km3, suggesting that the lake would fill rapidly (between 15 to 100 days depending on whether the event occurred during summer monsoon or winter dry season).
Some other research works suggested two values for optimum tilt angle, one for summer (rainy season in tropical region) and the other for winter (dry season in tropical region): ∅ ± 8° [12] 12] and ∅ ± 5° [13, 13] ('+' is for winter or dry season, while '−' is for summer or rainy season).
This winter, dry and warmer than usual, has disappointed skiers.
"You salt it in the winter, dry it in the winter, then you'd warm it up in the springtime and kind of age it in the summer.
Type A climates (the warmest) are differentiated on the basis of the seasonality of precipitation: Af (no dry season), Am (short dry season), or Aw (winter dry season).
