[1-19通用] 73N_05_下霰做不做雹击特检单？

天气开始连续降温几天，今天下起了小小的冰珠子，算不算冰雹呢？要不要做雹击特检单呢？我们去找找资料。。。

Graupel (GS):

   Graupel forms in the same way as hail except the diameter is less than 5 millimeters. It usually grows by soft hail processes.

霰(GS):

除了直径小于5毫米外，霰的形成方式与冰雹相同。它通常由软冰雹生长而成。

Hail (GR, A):
   Hail is dense spancipitation ice that is that least 5 millimeters in diameter. It forms due to ice crystals and supercooled water that freeze or stick to the embryo hail stone. Soft hail is more white and less dense since it has air bubbles. Soft hail occurs when hail grows at a temperature below freezing by ice crystals and small supercooled water and cloud droplets merging onto the hail. Hard hail occurs when liquid water drops freeze on the outer edges of the hailstone after the outer edge is above freezing. The freezing of supercooled water releases latent heat and this can result in the outer edge of the hail stone warming above freezing. Then the water refreezes creating solid ice. Hail will commonly have soft ice and hard ice layers when it is sliced open.

冰雹(GR):

冰雹是密集的降水冰，直径至少为5毫米。它是由于冰晶和过冷水冻结或粘附在胚胎冰雹石上而形成的。软冰雹白色较多，密度较小，有气泡。当冰雹在低于冰点的温度下生长时，冰晶、小的过冷水和云滴融合在冰雹上，就会发生软冰雹。当冰雹的外缘超过冰点后，液态水水滴在冰雹的外缘结冰时，就会发生硬冰雹。过冷水的冻结释放出潜热，这可能导致冰雹石的外缘温度高于冰点。然后水重新结冰形成固态冰。冰雹被切开时通常会有软冰和硬冰层。
