Narrative:

Due to wind shear, possible microburst, preceding aircraft reported 40 KT loss just as we experienced 30 KT gain, we executed a missed approach. Tower acknowledged our missed approach with climb on runway heading but we couldn't get an altitude assignment until on approach who assigned us 5000 ft where we leveled off. We were uncomfortable with the lack of altitude assignment from tower. There were no apparent conflicts.

Title: WIND SHEAR AND GAR.

Narrative: DUE TO WIND SHEAR, POSSIBLE MICROBURST, PRECEDING ACFT RPTED 40 KT LOSS JUST AS WE EXPERIENCED 30 KT GAIN, WE EXECUTED A MISSED APCH. TWR ACKNOWLEDGED OUR MISSED APCH WITH CLB ON RWY HDG BUT WE COULDN'T GET AN ALT ASSIGNMENT UNTIL ON APCH WHO ASSIGNED US 5000 FT WHERE WE LEVELED OFF. WE WERE UNCOMFORTABLE WITH THE LACK OF ALT ASSIGNMENT FROM TWR. THERE WERE NO APPARENT CONFLICTS.
